Tracking Mysterious Reload

This switch reloaded and I cannot figure out how.

From the show version (inserted below), it appears someone issued a 'reload'

-Only 2 people have login access to this device, both claim they did not issue a reload.

-Physical access to this room is monitored and I verified noone was in the room when this device reloaded (besides, resaet by switch would show return to rom by power)

-Device never lost power (besides, that would show return to rom by power)

-SNMP pub and priv are running with CiscoWorks

-I checked output interpreter, nothing seems out of the ordinary. I do not see any bugs for this device/IOS that will reload device. I see some that *crash*, but none that *reload* I enabled syslogging in case this happens again, but I was wondering if anyone has any suggestions to determine how this device reloaded? TIA for any assistance.

Post the output from the "show stack" command. If the switch actually crashed but somehow the reload cause is not being reflected correctly (due to a bug) in shpw version, you might see some system context from the crash.

Thanks for your reply Cisco da Gama. Here is show stack. Just for fun I ran this through Output Interpreter, which claims "There are no software or hardware bugs to report"

The "show stack" output looks clean and indicates no prior crash. I guess you will just have to wait until it happens again and you catch it happening if indeed this was not a manually initiated reload.

I suspected as much. Thanks for your time Cisco da Gama.
