Hello,
My router is a 7204 running IOS version 12.1(5)T12. I have an average of about 200 users connected
at all times. After running for about 12 - 24 hours, the cpu utilization rises considerably -
sometimes up to 98% and connections are lost. Any ideas? Below is part of an output of the show
tech-support command.
------------------ show process cpu ------------------
