Hi all,

In part of daily maintenance, i am checking my 3660 router cpu and memory checkups through "sh proc cpu" and "sh proc mem" command, i observed some times for a minute once, my cpu process is above 90%. I have taken both the processes list when as low as 3% and as high as 96%. I am unable to know which process is causing this high process usage. Can anybody give me clue?

The figure 96%/94%; reports that the 94% of cpu utilization is because of interrupts. So you will not see any process spiking it.

Here is the best url which explains how to troubleshoot high cpu issues.

http://www.cisco.com/warp/public/63/highcpu.html

It will answer all your questions.
