CORE ISSUE
We often come accross the situations where the Router or the switch crashes after turning the Debug on. Some people would like to know why this happens.
EXPLANATION:
When using debugging you want to have console logging turned off. Your console port is a very slow port and when you send the amount of messages that debugging sends, it over loads the console port and causes the processor to get backed up until it crashes.
RESOLUTION:
Going forward you want to turn logging back on and specifically turn console logging off - no logging console. If you enter the terminal monitor command via telnet you will be able to see the same messages without the processor being affected as much.
Here is a link with the proper steps to do a debug capture:
