[afnog] A router is crashing and rebooting itself

[David Chima]

Hello
I have a 1711 cisco router which was working very well. Suddenly one day the router froze and stopped working. I 
couldn't reach it on any port except the console. And it was in rommon.
I tried to reload the IOS through xmodem and rebooted it. I got the same results just as before.

Here is what I got/get, before/after IOS reload
