[c-nsp] Cisco 3750 Reboot Issue

[Arvind .cisconsp]

Do you see the same stack trace appear on all versions of code? If yes then
you are seeing the same issue across multiple codes and it could be a new
bug.

I have seen switches reload with similar (but not the same) exceptions due
to SNMP polling some OID's that were not really supported.

Do you know if there is any aggressive polling? Can you corelate the SNMP
poll's to memory leaking on the switch?

Getting TAC to decode the stack trace(s) will be the fastest way to identify
what could be causing the issue.
