When an SNMP request is made to the BIG-IP system, snmpd decodes the request and sends a request to the process that supplies the data to answer the SNMP request.


If the SNMP request times out before the process responds, the snmpd or SNMP subagent daemons might generate a core and restart. As a result, some data may be lost.


This occurs when using SNMP.


Restart snmpd using the command: bigstart restart snmpd.

Fix Information

This release corrects a condition that could cause snmpd or SNMP subagent daemons to generate a core and restart.
