Any packets from the TWAMP client will therefore be ignored. Similar to this, juniper boxes will also block any answers that are less than 52 bytes long, causing TWAMP test sessions to report a packet loss.

Test Configuration might fail even though the config file is having valid configurations
Product-Group=junos
Root cause; In test configuration flow we are calling mustd as "/usr/sbin/mustd -q /var/run/db/file.data /var/run/db/file.data+ -F -m" where we just copy the existing cog.db (generated out of committed config) as cdg.db+ , use it for testing the configuration passed, and remove it once the testing is done. This is creating the issue because the configuration is tested against the existing cdg.db. Fix would be to create the cdg.db fresh from the configuration to be tested and test the configuration against that. This new cdg.db should not replace the existing one in /var/run/db.

MX304:Bugatti: Observed spmbpfe core on RE1 when installed image on both the REs
Product-Group=junos
Sometimes cores are reported on backup RE during init after a reboot etc. When the backup RE initialization is being done and system is busy, some commands executed in context of spmbpfe are taking more time to complete due to the initial heavy lifting by the kernel, In this stage, if in case the commands from spmbpfe process do not complete for >2.5 seconds, then there are chances of spmbpfe cores. This is a temporary issue seen on backup RE during init time only. This may not be impacting because if in case spmbpfe process crashes due to this, it would restart by itself and continue to init and run once the initial high cpu condition has passed. It should not cause any functionality or performance impact; especially since it is reported only on backup RE.
