Minor		SNMP walk failure due to missing OID after FCO/TPA delete compression
Product-Group=evo
Severity=Minor		On all PTX Junos and Junos evolved platforms, an issue occurs when performing SNMP walks, resulting in the error No Such Instance currently exists at this OID. This is caused by a lifecycle management problem involving FCO (Factory Configuration Object) and TPA (Third-Party Attachment) objects. Specifically, when both FCO (IFDO) and TPA (IfSnmpInfo) are deleted in quick succession, only the FCO delete notification is sent, skipping the FCO modification callback that the TPA would typically trigger a delete event. As a result, the SNMP index mapping associated with the TPA is not properly updated, leading to missing entries during SNMP walks.

Product-Group=evo
Severity=Major		On all Junos and Junos Evolved platforms having Telemetry configured, the memory allocations in 512 bytes slab that are seen to be growing in problem state, are related to write on a unix domain socket (internal to application). Since the data is not read, the send buffer keeps growing and the associated memory does not gets released. Every telemetry response from the producer does a 1 byte write on this socket and over a period of time the send buffer gets full. The default size of the unix socket send buffer is set to 512MB. But there is no functional impact.

Major		Interface on mismatch speed configuration flaps
Product-Group=evo
Severity=Major		After system boot, continuous link flaps are observed if the optics are configured with an incorrect speed, typically 1G or 10G. However, when the correct speed is set on both ends (DUT and peer end), the link comes up normally without further flapping. This issue has been seen specifically with SFP+ optics (10G/1G) when mismatched speeds are configured. For example, configuring 1G speed for an SFP-10G-SR module results in link flaps instead of the link remaining down.

Product-Group=evo
Severity=Major		An LSI IFL remains in RPD even after being deleted by the interface manager daemon. It is visible in show interface routing but not in show interfaces, indicating that RPD still holds the IFL despite its removal elsewhere. rpd-agent does not send a delete message to RPD due to a reference count issue. Another daemon?likely l2ald?still holds a reference to the IFL. rpd-agent only sends the delete once all references are cleared, which doesn't happen in this case. The fix is to send a "delete pending" message from rpd-agent to RPD. RPD will treat this as a delete and remove the IFL, ensuring consistency across the system.
