Description (partial)


RP switchover without any crashinfo or kernel core dump saved on the primary RP.

We would see these messages in the log of the standby RP when it detects an heartbeat failure and resets the primary RP:

RP/0/8/CPU0:Jun  3 19:46:59.315 : psarb[329]: %PLATFORM-PSARB-6-GO_ACTIVE : Card is going active.
RP/0/8/CPU0:Jun  3 19:46:59.315 : psarb[329]: %PLATFORM-PSARB-2-MSG_HEARTBEAT_LOST : Slot 9 heartbeat lost


This happened on an XR12k running 3.6.2.
