The rpd dump file might be seen while processing the BGP updates
Product-Group=evo
The rpd crash files might be observed on Junos and Junos OS Evolved platforms while processing updates for BGP (Border Gateway Protocol) NLRI (Network Layer Reachability Information). This is observed only in specific circumstances like the route is first learned from an external BGP peer and a BGP policy with more than 4000 terms of different IPv6 (Internet Protocol) prefixes is present on the system. The issue may be due to the larger number of match terms in BGP import policy, to avoid the issue the policy terms matching IP addresses are minimal.

Commit fails with message "statement does not match patch" due to TOD mismatches between Primary RE and Backup RE
Product-Group=evo
When time-zone for the router is set as EST5EDT and if the TOD (Time-Of-Day) values under "event-options generate-events" are modified in different time zones, that is TOD configurations created on EST time zones are getting modified in EDT time zone, then it can cause commit failures. When such commits happens at different time-zones, internally, it generates a patch file and tries to load the patch at both RE. But due to different time zone, it is not getting excepted by backup RE.
