Hi,
I've got a problem with a 2960 : average cpu utilization of 50%. I can see the 50% load with this command : sh process cpu history but when I enter sh process CPU sort (5sec, 1min or 5min). I cannot see which process is loading the CPU. I don't understand why.
Thanks for your help.

Hello Chris,
probably most of cpu resources are used by SW interrupts look at the second number in 5 sec stats
sh proc cpu
CPU utilization for five seconds: 5%/0%; one minute: 6%; five minutes: 6%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
the bolded figure refers to SW interrupts
Hope to help

Guiseppe,
Yes this is an interrupt problem, but if I add up the process percentage, I'm far from 50%
This the result of sh process cpu sort :
CPU utilization for five seconds: 7%/1%; one minute: 42%; five minutes: 49%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
96 39974 8447 4732 0.49% 0.47% 0.47% 0 hpm counter proc
58 13245 31017 427 0.39% 0.20% 0.13% 0 RedEarth Tx Mana

I really don't understand : five minutes 49%, but I can't see any process in the 5Min column eating more than 0,5% (same with sh cpu process cpu sort 5min)
