CPU Usage High

Answered Question
Sep 17th, 2009

Sometimes CPU Usage on PIX-525 increased suddenly and I am not able to find out the reason.

I have checked Cisco Notes on this issue

and used commands like

sh cpu usage,

sh xlate,

sh xlate count

sh conn count

sh mem

sh processes

but still I am not able to find out the actual reason for High CPU Load. And I don't know What Should I do to reduce it.

reload is 1 answer but I think that should be the last option.

Please Help

I have this problem too.

Do a sh processes cpu-usage sorted

See which processes is hogging the most % CPU time. That may shed some light on the sudden increase in CPU Usage.

For my environment, normally it is the Logger because of a sudden increase in Firewall logs.
