23.4R2-S4 - List of Fixed issues

PR Number	Category: SRX-1RU System Hardware defects
1843413 Major	On SRX4600 platforms configured in Chassis Cluster, split brain condition will be seen under two conditions: 1. A node is isolated from the cluster and is reinstalled with Junos image using a USB and then re-joined into the cluster 2. A standalone SRX4600 is moved into a cluster The split brain condition will lead to potential loss of packets or routing inconsistencies.
PR Number	Category: QFX VC Datapath
1773425 Major	QFX5120, EX4650, EX4400, EX4100 Virtual Chassis (VC) platforms running Junos, drops Address Resolution Protocol(ARP) packets from remote leaf when Virtual Extensible LAN(VxLAN) encapsulated ARP packets are received from ingress port on one of the Flexible PIC concentrator (FPC) and egress port is an Aggregate Ethernet(AE) not having ingress port members on the FPC.
PR Number	Category: SRX1600 MACsec
1847366 Critical	On SRX3xx series configured with native-vlan-id, after upgrading the device to Junos version 23.4R1 or higher the native-vlan-id option is missing under the interface hierarchy. This leads to a syntax error, stopping users from setting the native-vlan-id.
PR Number	Category: "agentd" software daemon
1815195 Minor	On all Junos and Junos Evolved platforms, 23.2/23.4 release onwards, when gNMI is subscribed for the sensors, duplicate entries are seen. There is no traffic/service impact of the issue.
PR Number	Category: MX YT-ZF Linecards Interface Software Category
1846164 Major	In a scenario where a fiber link has transport devices to amplify the signal, excessive logging of alarms for an interface can occur. The transport devices will amplify the incoming signal, which isn't valid when the fiber has been cut. This causes the router to receive a good signal and Rx power but it contains no valid data. In response, the interface on the router will attempt to link up repeatedly and after failing multiple retries, which is set per platform, the router will attempt to reinitialize the data path. This causes multiple alarms from the optic to get set and then cleared resulting in alarm logs in the system logs. This can become excessive if the link remains down for an extended period of time. To avoid continuous logging to the system log, after a number of retries the logs will be suppressed. The interface will continue to attempt to link up including reinitializing the the data path, but without the logging. This will allow the interface to link up when the physical link is repaired, and at that point the logs will stop being suppressed
PR Number	Category: access node control protocol daemon
1841954 Major	The "show ancp subscriber detail" command is enhanced to display the port-up / port-down timestamps and port-down cause. It's neither an issue nor a regression an additional display output to enhance debuggability.
PR Number	Category: This gnats category is required to track NG-SPC PRS for SBU
1841859 Major	On Junos platforms, specifically MX240, MX480 and MX960 supporting MX-SPC3 (Services Processing Card) service cards, if PIC (Physical Interface Cards) receives high traffic enough to make CPU (Central processing unit) almost 100% busy, it will go down, triggers flowd core-dump and cause network impact.
PR Number	Category: the replication daemon (repd) for Shared Memory-base
1797189 Major	On all Junos and Junos Evolved platforms, repd core observed (in the "from" release) during ISSU.
PR Number	Category: BBE routing
1826324 Critical	On all Junos and Junos Evolved platforms configured with subscriber management with GRES (Graceful Routing Engine Switchover) enabled, the subscribers will not come up after an ungraceful switchover as RE0( Routing Engine) went down and FPC's rebooted.
PR Number	Category: Bi Directional Forwarding Detection (BFD)
1807182 Minor	On all Junos and Junos OS Evolved platforms with BFD (Bidirectional Forwarding Detection) authentication enabled, interface flap is observed and subsequent protocols will go down. This could result in traffic disruption for that protocol leading to outages.
PR Number	Category: Border Gateway Protocol
1793714 Major	On all Junos and Junos Evolved platforms, when 'delay-route-advertisements always-wait-for-krt-drain' is configured, the EoR (End of Record) from the source peer of the routes is not received in the BGP (Border Gateway Protocol) peer which is sent by a BGP speaker to indicate the end of a record or a sequence of updates. This is due to the BGP router advertiser being stuck in the wait-for-inbound-convergence state, which may cause the KRT (Kernel Routing Table) queue to get stuck, thereby halting the advertisement of BGP routes.
1826685 Major	On Junos and Junos Evolved platforms, when a catastrophic Border Gateway Protocol (BGP) configuration change occurs, creating a new peer structure due to this configuration change, the BGP state transitions from open-sent to established multiple times (until the local device finishes cleaning the old BGP session). This results in traffic impact as the peer is reset multiple times (until a new peer connection is established).
1839318 Major	On all Junos and Junos OS Evolved platforms, setting next-hop (NH) doesn't work with BGP (Border Gateway Protocol) import policy, if the policy is also modifying community. Due to this, the traffic will not be forwarded to the intended NH.
1841090 Major	On all Junos and Junos Evolved platform, the rpd process will crash when an IPv6 (Internet Protocol Version 6) BGP (Border Gateway Protocol) - Labeled route is leaked using rib-groups to VRF (Virtual Routing and Forwarding) table and auto exported to IPv6 VPN(Virtual Private Network) table.
1845169 Major	On all Junos and Junos OS Evolved platforms, for MPLS L3 VPN's (Multi Protocol Label Switching L3 Virtual Private Network) if static route-target-filter as local is configured, BGP (Border Gateway Protocol) stops advertising VPN routes to EBGP (External BGP) peer.
PR Number	Category: Track PRs in BGP BMP area & is part of BGP inside RPD.
1807892 Major	A route can get stuck in
1839288 Major	On all Junos and Junos Evolved platforms, when "clear bgp statistics" command is issued while one or more BMP peers are coming up the soft_assert will be hit. This issue has no impact on the traffic or services.
PR Number	Category: BBE Remote Access Server
1826901 Major	On all Junos MX platforms, the authd process would crash if it attempts to access the subscriber management database (SDB) while the SDB is undergoing re-initialization due to a problem. Due to this, new subscriber login will be affected possibly for few seconds.
PR Number	Category: EVO L3 routing for BCM XGS Platforms
1828017 Minor	On all Junos and Evolved platforms, in a scaled setup when the "clear bgp neighbor all" command is executed or "restart l2-learning immediately" is executed, the pfemand crash will be seen which leads to the restarting of the Flexible Packet Forwarding Card (FPC).
PR Number	Category: MX304 Chassis specific platform
1802195 Major	On Junos Evolved platforms and MX platforms with LC9600, MPC11 or MX304, the mapping optics temperature sensor name with ifd name is not correct. This PR is for correcting the behaviour and does not have any service impact.
PR Number	Category: MX304 interface specific
1861672 Major	On MX304 platforms, random interfaces operating at 100G speed will remain down after an FPC (Flexible Port Concentrator) reboot, resulting in traffic loss.
PR Number	Category: MX304 line card platform software
1849915 Major	On Junos MX204, MX304, MX2010, MX2020, MX10004, MX10008, MX10016 with MPC11, LC2301/LC9600, LMIC16 and LC480 line cards, when installing and uninstalling specific telemetry sensors that export data from LC (Line Card), a few bytes of memory are allocated but not freed, leading to a memory leak. This issue is seen when "sensor-based-stats" is configured and LSP (Link State Path) flaps occur. Each flap triggers repeated installation and uninstallation of the telemetry sensor, accelerating memory consumption. Over time, this exhausts the memory allocated to aft-ulcd process causing FPC (Flexible PIC Concentrator) to reboot.
PR Number	Category: MX Platform SW - FRU Management
1816912 Major	On Junos platforms, RE detects IIC read or write failures and triggers a minor alarm " RE1 IIC access alarm" during commit operations
PR Number	Category: MX Platform SW - UI management
1805508 Major	The "show snmp mib walk jnxOperatingFRUPower" is NOT correctly updated for CB components.
PR Number	Category: Class of Service
1828018 Major	An unrelated commit will trigger flap of protocol adjacencies (BFD, LFM, LACP, etc.) over aggregated Ethernet interfaces if scheduler-map is attached to aggregated Ethernet interfaces (this commit shouldn't necessarily be the first, but it may be). The issue is typically seen only once, the subsequent commits do not trigger further flaps, unless child links of the affected aggregated Ethernet interfaces flap.
1836528 Minor	On all Junos and Junos Evolved Platform, forwarding-class (FC) identifier (id) goes out of sync between the Routing Engine (RE) and Packet Forwarding Engine (PFE) when software upgrade is performed. When In Service Software Upgrade (ISSU) is performed, FC id goes out of sync between the RE and PFE impacting all class-of-service (CoS) features using FC id. When manual software upgrade is performed (without using ISSU) , this issue will be seen as a cosmetic display issue where the order in which the FC configurations are displayed will differ.
PR Number	Category: QFX Access Control related
1840988 Major	On Junos EX2300, EX3400, EX4100, EX4300, EX4400 platforms, a misconfiguration in CWA (Centralised Web Authentication) occurs when authentication web-management is not configured, leaving stale entries until the authentication session clears, the interface where the client device is connected flaps or the end user MAC ages out. If memory is exhausted due to these stale entries, a PFE (Packet Forwarding Engine) process crash will occur, impacting traffic on all ports.
PR Number	Category: OpenSSL and related subsystems
1815253 Major	The OpenSSL project has published security advisories for multiple vulnerabilities. Please refer to https://supportportal.juniper.net/JSA88107 [juniper.net] for more information.
PR Number	Category: DNS software support.
1816951 Minor	On SRX and vSRX platforms, when unified policy ( dynamic applications) is configured along with DNS profile configuration, a crash is observed.
1826129 Major	On all Junos SRX and vSRX series platforms Juniper networks Deep Packet Inspection (JDPI) gives events per packet. Domain Name System Firewall (DNSF) plugin is leaking memory while processing those events.
PR Number	Category: CoS support on DNX
1850907 Major	On Junos OS ACX5448 and ACX710 platforms, the DEI(Drop Eligibility Indicator) bit in the VLAN(Virtual Local Area Network) header for the inner VLAN tag is being set incorrectly. As a result, packets with the DEI bit set will be dropped downstream.
PR Number	Category: Layer 3 forwarding, both v4+v6
1849241 Major	On Junos OS ACX5448 and ACX710 platforms with native-vlan-id configured over L3 (Layer 3) interface with AE (Aggregated Ethernet), the device forwards packets with native VLAN (Virtual Local Area Network) tagged in the packet i.e. packets will be egressed out of the interface configured with VLAN matching the native VLAN resulting in the peer the device will drop the packet.
PR Number	Category: jdhcpd daemon refactored for evo
1816246 Major	Under certain conditions, the DHCP session database becomes unstable or JDHCPD not getting IFL/IFD events which cause DHCP packets to fail to route to the kernel and then leads to DHCP packet drop.
PR Number	Category: EVO L2 Control Plane PRs
1828741 Major	On all Apstra polled Junos Evolved devices experiencing heavy load. Specifically, when L2ald and l2ald-agent were engaged in high-volume data exchange over the management socket, L2ald becomes unresponsive.
1844623 Major	On all Junos and Junos OS Evolved platforms, when decapsulate-accept-inner-vlan or encapsulate-inner-vlan or both knobs are configured for a VXLAN (Virtual Extensible Local Area Network) and when any action corresponding to MAC-IP entries cleanup takes place, the MAC-IP entries will not be cleaned up from kernel. This will result in anomalies in device and could also lead to a core crash.
1853868 Major	When EVPN (Ethernet Virtual Private Network) routing instance has IRB (Integrated Routing and Bridging) interface with IPv6 (Internet Protocol version 6) address, ICMPv6 NA (Neighbour advertisement) reply from IRB IPv6 address doesn't have router flag. The ICMPv6 NA from IRB IPv6 should have router flag.
PR Number	Category: mgd, ddl, odl infra issues
1825793 Minor	"show system configuration rescue" may show strange "Last changed" timestamp. It may happen under any time zone potentially and looks like there are some patterns. In case of "Asia/Tokyo", Last changed timestamp may show "1970-01-01 08:59:59 JST".
PR Number	Category: EVPN control plane issues
1796532 Major	On all Junos and Junos Evolved platforms, duplicate mac-ip detection for IRB IP is not working since the IP move is not triggered after adding an IP address to the IRB interface.
1816672 Major	There are multiple EVPN instances each having separate IFL of AE IFD. AE is configured with per-esi lacp-oos-on-ndf on the AE IFD. On deactivating one of the instances, LACP on non-DF router comes out of "out-of-sync" state, causing CE device to move to Collecting distributing.
PR Number	Category: EX4100 PFE
1831813 Major	On Junos EX platforms, the PFE's (Packet Forwarding Engine) handling of NEWSYSLOGD signals during UKERN file archiving is inefficient, leading to repeated memory allocations and subsequent memory leaks.
PR Number	Category: EX4100 RE, Platform Infra, Drivers
1848292 Major	On the Junos EX platform, fan overspeed alarms may intermittently trigger as fan speeds exceed and fall below the set threshold, with no impact on service
PR Number	Category: EX interfaces issues
1788328 Major	On all EX platforms with Virtual Chassis (VC) and Graceful Routing Engine Switchover(GRES) enabled, if during failover the secondary Flexible Physical Interface Card Concentrator (FPC) gets rebooted then there will be traffic loss of 20 seconds more than the expected traffic loss (1to2 seconds).
1793137 Major	On EX4100-24T, EX4100-48T, EX4100-48P, EX4100-48MP, and EX4100-24MP platforms, after a power cycle, the uplink interfaces may go down with a LOCAL-FAULT alarm. This issue is caused by an anomaly in the Broadcom PHY (bcm82756) third-party SDK code used on these devices.
1805100 Major	On EX4300-MP platforms in non-mixed VC mode, when the VC connection is established between the platforms, the ports don't pass traffic, which leads to minimum traffic loss.
1849992 Major	On EX4400 devices, inserting SFP+-10G-BX10-D/U or SFP+-10G-BX40-D/U into the 4x25G uplink module causes all ports on the Physical Interface Card (PIC) 2 to go down.
PR Number	Category: EX4400 PFE software
1854253 Major	On Junos EX and QFX platforms when DHCP (Dynamic Host Configuration Protocol) option 82 settings are enabled under dhcp-security, hosts fail to get an IP address from the DHCP server.
PR Number	Category: EX4400 platform
1826615 Major	On all EX4400 platform, all time sensitive protocols are getting flapped due to process call getting stuck in System Management Bus (SMBus).
1844354 Major	On EX4400 platforms with Media Access Control Security (MACsec) environment configured, if a transceiver is removed and then inserted again, MACsec will not work and a core file will be generated.
PR Number	Category: Issues related to EX MACsec

PR Number	Category: PFE EVPN / VxLAN related issues on EX platforms
1852215 Major	On EX4400/EX4100/EX4650/QFX5120 platforms VoIP (Voice over IP) phones do not receive an IP address when the VXLAN (Virtual Extensible LAN) access port on the switch is configured as VoIP port causing voip tagged traffic on VXLAN access port to be dropped.
PR Number	Category: Express PFE FW Features
1830706 Major	On all Junos platforms, when a filter instance is modified or deleted, there should not be any old Packet Forwarding Engine (PFE) instances. However, during these operations, old PFE instances are being incorrectly assigned, resulting in incorrect memory address allocation. This leads to an Flexible PIC Concentrator (FPC) crash after committing the configuration, causing traffic loss.
PR Number	Category: Express PFE Services including JTI, TOE, HostPath, Jflow
1830575 Major	On all Junos platforms, the dcpfe crash is seen with a core-dcpfe dump when the ukern_trace handle buffer size is set to 10000. It is a rare issue.
PR Number	Category: Express PFE L2 fwding Features
1802615 Major	Unreachability to VRRP gateway IP causes end host connectivity issues. This issue impacts unicast packets addressed to the VRRP gateway IP on QFX10002-36Q, QFX10002-72Q, QFX10008, and QFX10016 platforms. It is triggered by VRRP configuration and unicast traffic to the gateway IP. It impacts both IPv4 and IPv6 traffic.
PR Number	Category: SRX1500 platform software
1845143 Major	On the Junos SRX1500 platform, the device reboots spontaneously because the watchdog is triggered unnecessarily.
1845407 Major	On SRX1500, "show snmp mib walk jnxOperatingTemp" and "show snmp mib walk jnxFruTemp" will not show up temperature reading for PSU temperature.
PR Number	Category: SRX4100/SRX4200 platform software
1823978 Major	On Junos SRX platforms, due to common cache feature, more accurate IP address resolutions are being updated to the PFE (Packet Forwarding Engine). However, this led to increased CPU utilisation by the nsd (Network Services Daemon) process. Due to high CPU load, the newly resolved IP addresses may not be updated promptly to PFE leading to traffic loss.
PR Number	Category: Interface Information Display
1631200 Major	IFL counter has a counter named "IPv6 transit statistics". It can be confirmed on "show interfaces extensive" command output. However, this counter is originally for IPv6 total statistics(transit + local) and the counter name was wrong from the first. On older releases like 19.1R1, as the support for IPv6 local stats was not available the local stats was always zero. So, the meaning of the counter name was the same to the counting content coincidentally. In latest releases support for IPv6 local stats has been added but the counter name was not changed. As the local stats will not be zero the difference between the meaning of the counter name and the counting content started being visible.
PR Number	Category: Libjtask for RPD tasks, scheduler, timers, memory, and slip
1826194 Major	On all Junos and Junos Evolved platforms, rpd crash is observed during upgrade or restart since kernel takes more time to update ifstate information.
1843627 Critical	On all Junos Evolved platforms, a memory leak occurs when a routing instance configured with "vrf-table-label" is deactivated and then reactivated, followed by a Routing Engine (RE) switchover on dual RE systems. This issue causes a slow memory leak in the system.
PR Number	Category: MX Inline Jflow
1813925 Major	On all MX platforms with MPC10/MPC11/LC9600, MX304 and EX9200-15C platforms, when any sensor configuration on protocols, for example, MPLS LSP, is configured and removed over a long period, the aftd-trio process starts a memory leak and eventually causes FPC to reboot.
PR Number	Category: Kernel software for AE/AS/Container
1840734 Major	On all Junos platforms which support PS over RLT, after modifying or deleting and re-adding a logical interface on RLT interface, the logical interface remains down and the following log messages is seen in the messages log:DCD_CONFIG_WRITE_FAILED: IFL rlt0.0 configuration write failed for an IFL ADD: File exists after configuration change.
PR Number	Category: Integrated Routing & Bridging (IRB) module
1815250 Major	Due to a conflict in the config between the VXLAN (Virtual Extensible LAN) hardware token and the VLAN (Virtual Local Area Network) traffic loss could happen as consequence of wrong path for ARP (Address Resolution Protocol)
1827648 Major	On all Junos QFX series platforms in an EVPN (Ethernet Virtual Private Network) VXLAN (Virtual Extensible Local Area Network) setup with CRB (Centralized Routing Bridge) architecture, ARP packets are not being learned, leading to traffic forwarding issues. This problem arises when ARP packets are sent from the firewall to the spine switches. The issue is linked to IRB (Integrated Routing and Bridging) handling and bridge domain re-incarnation, which triggers ARP request failures and impacts L3 forwarding.
PR Number	Category: ISIS routing protocol
1837289 Major	On all Junos and Junos OS Evolved platforms configured with "protocols isis overload advertise-high-metrics" (without timeout) and graceful-restart, IS-IS (Intermediate System to Intermediate System) will start advertising high link metrics immediately as expected. However, when IS-IS is in graceful restart mode either via GRES (Graceful Routing Engine Switchover) switchover or restart routing, the high link metrics are not advertised and IS-IS continues to advertise the usual link metrics even when IS-IS graceful restart is completed. When the issue is hit, the node configured as an overload might be used for transit traffic based on the IGP metric.
1841108 Major	On all Junos and Junos OS Evolved platforms, in an ISIS(Intermediate System-Intermediate System) graceful restart scenario, helper node sends and programs its locally configured hold-time (180 secs) instead of the "Restart-duration" received as hold-time from DUT (210 secs), due to this incorrect update, the hold timer expires at the helper node before the GR (Graceful Restart) is complete on DUT and it causes a flap of ISIS adjacency on peer/helper Node.
PR Number	Category: jdhcpd daemon
1714260 Major	On all Junos and Junos OS Evolved platforms, when Dynamic Host Configuration Protocol (DHCPv4) Relay is configured with forward-only mode along with "trust-option-82", DHCP-relay should not add another option 82 to the packet sent to the DHCP server. The DHCP server upon receiving the packet with two option-82 will respond only with 1st header of option-82 which might get dropped by the relay, thus the packet is not forwarded to the DHCP client and the DHCP session won't get established.
1833148 Major	On all Junos and Junos Evolved platforms when roaming between Wireless Access Points (WAP) and binding server is down, server failover does not happen in an active-server group even when "allow-server-change" is configured on Dynamic Host Configuration Protocol (DHCP) relay agent.
1854827 Major	On all Junos devices, management interface does not get an IPv4 from Dynamic Host Configuration Protocol (DHCP) even if the interface is bound. When power cycle or reboot is triggered, management is lost without traffic impact.
PR Number	Category: jpppd daemon
1854387 Major	On Junos and Junos OS Evolved platforms, the jpppd (Juniper PPP daemon) process crash will be seen after a certain time of subscribers login/logout. The issue could be seen with the applications that write their private data in /mfs/var/sdb/shmem/sdb_intf.ad.db.
PR Number	Category: SRX power-mode-ipsec/power-mode-expresspath(PMI/PME)
1833746 Major	On SRX1500/SRX1600/SRX2300/SRX4K/SRX5K platforms with PMI (PowerMode IPsec) enabled, IRB (Integrated Routing and Bridging) traffic in Layer 2 switch mode is not supported, resulting in packet drops.
PR Number	Category: Flow Module
1828819 Major	Application quality of service (AppQoS) rate limit in PowerMode IPsec (PMI) mode on Junos SRX5K and SRX4600 drop packets unexpectedly due to internal issue.
1846897 Major	In a vSRX High Availability (HA) setup, a high volume of orphaned backup sessions will be exhausting session resources. This happens because the timeout value for backup sessions is typically set to the minimum of 8 times the active session's timeout value and 1800 seconds. If the orphaned backup sessions accumulate and exhaust the session resources, the system will fail to allocate new sessions.
1856521 Major	On all SRX platforms in a cluster, during an HA switchover, especially with a large number of sessions (e.g., greater than 1M), CPU utilization spikes temporarily, reaching up to 95% for a brief period. This occurs during the primary node's reboot or HA switchover. The CPU spikes cause partial service impact, which can affect traffic for a short time during the event. Once the session scan is completed, CPU utilization should return to normal as the session synchronization and cleanup processes are finalized, reducing the load on the system and restoring traffic flow to its usual performance levels.
PR Number	Category: Firewall Policy
1844191 Major	On all SRX platforms, if has one DNS server which was unresponsive and another which refuse responses or responds with a non-positive error code, the FQDN-based security policies will not work as expected and packets might hit a different allow/deny rule.
1847877 Major	On all SRX platforms, the Management Daemon (mgd) core is seen after a large number of configurations executed when configuring the network address book and attach it to a security policy.
PR Number	Category: RPM, TWAMP feature related to SRX specific design
1830290 Major	On SRX4600 platforms when Real-time Performance Monitoring (RPM) related configuration is committed, 'gencfg no msg handlers for gencfg msg' log messages will be generated. This will not have any functional impact.
PR Number	Category: User Firewall related issues
1845506 Major	On all SRX platforms with source-identify and logging enabled, the PFE (Packet Forwarding Engine) crashes if the source identity username and group-names exceeds certain count and length. The system self-recovers after the issue is hit.
PR Number	Category: IPSEC/IKE VPN
1805690 Major	Stale IPSEC tunnel entry can be reported on the backup node's PFE
1818197 Major	On SRX platforms, if the outgoing interface of the Internet Protocol Security (IPsec) Virtual Private Network (VPN) peer goes down when the peer device operates in the Network Address Translation-Traversal (NAT-T) environment and the default route points to the secure tunnel interface (st0), there are chances of an internal routing loop which will lead a srxpfe process crash caused by the Memory Buffer (mbuf) corruption.
1848834 Major	When IPSEC (Internet Protocol Security) is enabled, during a restart or failover, a failure in adding a node might occur while attempting to read from the Database. Consequently, when a deactivate operation is performed on the configuration, the system attempts to delete a node that was never successfully added. This mismatch between the system state and the database triggers a core dump.
1851652 Major	On all SRX platforms, if the active VPN (Virtual Private Network) tunnel is disabled or failed, the device does not correctly transition to negotiate with an active gateway. Instead, it continues attempting negotiation with the inactive gateway, leading to failed tunnel establishment.
PR Number	Category: Security platform jweb support
1837925 Major	On Junos SRX (SRX1500, SRX4600, SRX4100 and SRX5K's) platforms, image upload via J-Web fails with an error "Access Error: 502 -- Bad Gateway".
1840753 Major	On all Junos SRX platforms, When J-Web is in use and user continously navigates between monitor -> interfaces and dashboard without waiting for the interface response. This leads to CPU (Central processing unit) spike.
1851362 Major	Due to GMT+x or GMT-x time zone is not supported, J-Web will fail to load after upgrading SRX.
1858466 Major	On all SRX platforms, Juniper Secure Connect (JSC) clients may fail to establish a VPN session after successful authentication if more than 20 concurrent connections per client IP are active. In a NATTed environment, the 21st connection will fail, and the customer must retry.
PR Number	Category: Layer 2 Control Module
1855088 Major	In Junos EX and QFX platforms, when a port is configured with Inter-switch-link (ISL) trunk and the Ethernet ring protection switching (ERPS) protocol is enabled on the port, the commit command fails, causing the commit-check daemon process to crash and preventing the new configuration from being applied. This doesn't impact the devices traffic, performance, or management.
PR Number	Category: Layer2 forwarding on EX/NTF/PTX/QFX
1820882 Major	On all Junos and Junos Evolved platforms, in Ethernet VPN (EVPN) multihoming scenario with mac-pinning enabled, traffic drop will be seen when the Designated Forwarder role (DF) is changed.
PR Number	Category: Label Distribution Protocol
1817712 Major	On all Junos and Junos Evolved platforms Label Distribution Protocol (LDP) sessions are not formed due to the configuration of "container-lsp" with an already existing configured lsp-template which has "ldp-tunneling" knob enabled.
PR Number	Category: Issues related to Junos licensing infrastructure
1823449 Major	On all Junos OS Evolved platforms, when a reboot is performed, the license usage is not set for features like OSPF, BGP etc. Feature usage is not set again unless the commit is done.

1843602 Major	On all Junos platforms, a TCP (Transmission Control Protocol) connection issue occurs between the device and syslog server after an idle period exceeding 2 hours. The session gets terminated and remains in a closed state without initiating any new session until the syslog server configuration is deleted and added again. This impacts disruption in log forwarding to the remote syslog server.
1848106 Major	On all Junos and Junos OS Evolved platforms, eventd process crashes is observed. This happens when eventd process is processing the flooding of out of memory logs generated by any of the processes running on FPC (Flexible PIC Concentrator). This is traffic impacting depending on the process with memory issues.

1631579 Critical	A system equipped with specific line cards, the line cards will be stuck in the 'Present' state and later go 'Offline' after the line card or router is rebooted. Ideally, the Line Card should go 'Online' instead it goes 'Offline'.
1807939 Minor	RE uses enhanced mode RCMD protocol to communicate with the FPCs, by default. However, the FPC line cards do not understand the enhanced mode rcmd protocol. Hence the below logs generated. daemon.err rshd[618008]: Second port outside reserved range. After the failure, the communication falls back to the normal mode from enhanced mode.There is no production impact due to this issue. The fix has been implemented in the resolved versions, wherein the communication between RE and the FPC will now happen through the normal mode by default.
