snmpd might occasionally experience a thread deadlock conditions and would be restarted (with a core dump) by sod.
snmpd occasionally becomes unresponsive for the duration of the configured snmpd heartbeat timeout.
This can occur during a SNMP configuration change.
After a SNMP configuration change on the BIG-IP system, the deadlock timing issue can avoided by manually restarting snmpd.
snmpd no longer becomes unresponsive for the duration of the configured snmpd heartbeat timeout during configuration changes.
