Symptoms

When a BIG-IP system is being shutdown or rebooted, or the sflow_agent is exiting for some other reason, the sflow_agent daemon may crash and produce a core.

Impact

sflow_agent might crash. There is no effective impact, since the BIG-IP system or process is already in the process of shutting down.

Conditions

Shutdown or restart of the BIG-IP system, or termination of the sflow_agent for any other reason

Workaround

None.

Fix Information

During shutdown, the sflow_agent daemon does not crash.
