Hello there,

guess the reaso is in the show ver:

System was restarted by error - Software Forced Crash Exception (0x0700)!, PC 0x43E490

If this is under a contract open a SR and look in flash memory there should be a file named crashinfo_datetime.

Upload that one to the SR and wait for an answer. You might have configured a feature which activates a bugged routine causing the reload.

If you do not have a contract but the hardware is still under warranty, call Cisco TAC they will let you open a case and provide support.

If out of contract and out of warranty, buy a contract and start from step 1 :-)

Hope this helps

Fabio

I cannot find any matching bug based on the stack trace posted. Since this switch is EOL already, you can upgrade the switch to a later version like 12.2(44)SE6 to see if the problem persist. If the problem is not fixed, you next choice is to replace it.

Ya, it make sense what you said. I just wanted to see what are the possible options. I have taken the switch out of production already, was hoping to know what possible thing went wrong for my future reference.
