1517081 The rpd calculates available memory wrongly when running in 64-bit mode
Product-Group=junos		When rpd is operating in 64bit mode, the available memory calculation is incorrectly limited to 32GB by the kernel. On systems with memory greater than 32GB (e.g. 48GB or 64GB) it can cause incorrect output from "show task memory" CLI command and syslog messages. The rpd may report values greater than 100% in use when it allocates more than 32GB of memory. This may also cause rpd to log JTASK_OS_MEMHIGH syslog messages. Example output with >100% usage: user@router> show task memory Memory Size (kB) Percentage When Currently In Use: 5321268 44% now Maximum Ever Used: 37059547 107% 20/06/11 00:27:51 Available: 34359738 100% now Example syslog message: rpd[4119]: JTASK_OS_MEMHIGH: Using 37044285 KB of memory, 107 percent of available

Product-Group=junos		On all Junos and EVO platforms running BGP, when a specific route is received from multiple places under a VRF, multipath route is getting formed even though the BGP route selection algorithm has the active route with higher local preference. Once multipath is formed, the traffic forwarding is happening based on that, and it may result in some traffic going to an unwanted path. Please refer to KB37775 [juniper.net] for more details.

1548626 When Junos OS software is upgraded to Junos OS Release 20.3, you might see the error "ERROR: Failed to setup symlinks in alternate root".
Product-Group=junos		Older version JUNOS upgrade to 20.3R1 and later version will appear this "ERROR: Failed to setup symlinks in alternate root" warning. This is because during install 20.3R1 JUNOS package, it will extract a 'kernel' file at /altroot/ which lead to it create the /altroot/kernel symlink fail. it is by design, the 20.3R1 is successfully installed without the symlink.

1630886 LLDP packets may be sent with incorrect source MAC for RETH/LAG child members
Product-Group=junos		On all platforms, when LLDP is run on child members of LAG/Redundant Ethernet (RETH) interfaces, LLDP packets may not be sent out with interface hardware address as source MAC. Instead, packets will be sent out using LAG/RETH interfaces MAC address. So, in case if the RETH/LAG interface MAC address changes, the source MAC address of LLDP packets will also change dynamically. Which will affect any service that relays on LLDP.

1575231 The fxp0 interface of an SRX550 in cluster might become unreachable from an external network
Product-Group=junos		On SRX550 configured with chassis cluster, fxp0 interfaces might not be reachable from external management interface when the fxp0 and redundant Ethernet(reth) interfaces are in separate routing instances. This is because there is no ARP entry for the reth interface in fxp0 ARP table. As a result of this, SRX cluster cannot be accessed from an external management network.

PR NumberSynopsisCategory: MX10003/MX204 Platform SW - Chassisd s/w defects
1575029 The chassisd process might have memory leak issue and crash in long term
Product-Group=junos		Starting 19.4, On MX204/MX10003 and SRX4600 platforms, the chassisd process on the primary Routing-Engine (RE) keep leaking memory without any trigger. When chassisd memory usage reaches 3.5GB it may crash and trigger RE switchover. In some production cases, the RE switchover has triggered temporary traffic impact even on NSR/GRES enabled systems. The rate of memory leak is depending on how many optics/SFPs the system has. Rate of leak = 'Number of optics/SFPs under the system has' * 16Bytes per every 6 seconds. On older Junos (19.3 and earlie), the leak is happening when interface configuration/reconfigurations or change in PIC mode or port speed configuration or SFP initilization is done.

Product-Group=junos		On all MX series platforms, in a rare case when CoS classifier binding message received before logical interface family creation message to PFE, traffic might be classified with default classifier instead of custom classifier. Due to this, traffic may not be classified and mapped to the right Queue resulting in not right CoS treatment for the traffic.

1632132 The BGP session might flap after rpd crash with 'switchover-on-routing-crash' and NSR enabled in a highly scaled environment
Product-Group=junos		On all Junos platforms that support NSR(Nonstop active routing), when 'switchover-on-routing-crash' is enabled, the rpd process crash will lead to Routing Engine switchover. In a highly scaled environment(about 15~19 million BGP routes), BGP(Border Gateway Protocol) session which is still sending update packets of size more than 2k might flap even when NSR is enabled. This might lead to loss of traffic till the BGP session converges after the flap. This does not happen always but happens sporadically. The switchover can be either due to rpd process crash or when switchover is performed manually.

The intended router might not be the VRRP master instead the peer router with less priority will be master. The route states are not correct because "route add" messages are not received at 'vrrpd' after activation of the interface. When the interface is activated an interface route is created for the address configured on the interface, 'vrrpd' will receive the addition and then update the track route state accordingly. When this is not being received at 'vrrpd' tracking routes might become unknown.
