Try using "show processes cpu sorted" to see what the top processes are. If your still unsure, post the first page of that output for review.

Rojer-bkk,
One of the most common causes behind seeing this type of output is that the cpu is high under interrupt. If you look at the 5 second value on the 'show proc cpu' output you will notice that there are actually two numbers listed there (something like this 50%/45%). These two numbers are an indication of the total CPU utilization over a 5 second interval (50%) and the amount of the total that is due to interrupts (45%). The most common cause of high CPU under interrupts is traffic being forwarded by the device. There are a number of commands that can assist in troubleshooting this type of a problem, whether it is caused by traffic or some other issue. Take a look at this document for some additional information:

I believe this has been answered. If you have questions, please feel free to post the output of the 'show proc cpu sort' as was suggested.
