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 count
sh conn count
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.
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.
