Cisco Router 100% cpu utilization

I run #sh proc cpu, can see:

CPU utilization for five seconds: 100%/81%; one minute: 87%; five minutes: 80%

but I cannot find in the any high cpu process according to the PID.

Do you know why?

The high cpu utilization make the logn ping time even timeout.

Re: Cisco Router 100% cpu utilization

It normally over 80% but I cannot find which process has high CPU, all process around 0.xx%.

When the BGP Scanner run, it touch 100%. I think BGP Scanner run is normal, just don't know what process already occupy 80% cpu usage.

Re: Cisco Router 100% cpu utilization

Hi, if you use the "show proc cpu sorted" command you would get the list sorted with the highest % at the top, would be easier to see if you might have just missed it.

And next question, what kind of router do you have, and what does it do.

Re: Cisco Router 100% cpu utilization

Hi

Can you paste the output of show processes cpu and show processes cpu sorted ?

Re: Cisco Router 100% cpu utilization

show processes cpu sorted not work.

here is sh proc cpu.

CPU utilization for five seconds: 73%/70%; one minute: 75%; five minutes: 75%

Re: Cisco Router 100% cpu utilization

This is a much cleaner way to get only the high processes.

show process cpu | exclude 0.00%__0.00%__0.00%
