Description (partial)

The affected device reports through the system logs that SNMP crashes due to signal 11:

%SYSMGR-2-SERVICE_CRASHED: Service "snmpd" (PID 27822) hasn't caught signal 11 (core will be saved).

Core files are generated in some events, use the 'show process log' command to see if a core was created or not:

# show processes log

VDC Process          PID     Normal-exit  Stack  Core   Log-create-time
--- ---------------  ------  -----------  -----  -----  ---------------
  1 snmpd            #####             N      Y      Y  <Date>
  1 snmpd            #####             N      N      N  <Date>
Use the 'show cores vdc-all' command to check for core files.

If a core file is present engage TAC to assist with core retrieval, decode, analysis and to identify if this software bug impacts the device:

# show cores vdc-all

VDC  Module  Instance  Process-name     PID       Date(Year-Month-Day Time)
---  ------  --------  ---------------  --------  -------------------------
#    #       #         snmpd            #####     <Date>

SNMP cache is deleted at the time of the crash. The core decode is required to identify if SNMP cleared the cache, please engage TAC to determine in the device is affected by this bug.
