Hi Anoop,

               Is this for a VM or Physical appliance. Restart is caused by watchdog as the message says.

Hi Aravind,

This is HW platform S200-20.

Anoop

Hi Aravind,

Noticed Bug#240320(The proxy experiences a watchdog restart in the SNMP subsystem in environments with more frequent connection timeouts) being fixed in 6.6.5.10 patch. Is this applicable to our issue ?

Regards,

Anoop

Hi Anoop,

              Not easy to confirm by looking at the mini-context alone. Since full core is available, it will be better to get it escalated along with that. I was having a doubt but that only applies to VMs even though the crash messages were exactly same. It was related to some mismatch in watch dog reset (Bug#251550) . If this is the issue, then the fix is not yet ready. I will recommend for escalation to get this checked.

Hi Aravind,

Thaks for your advise. Logged one Symantec case.

Regards,

Anoop
