High CPU on procurve 5406

Hi,
How can I get more information on what process is using up my cpu? I have had my 5400zl switch (with premium routing) sit at 60%, 70%, or one time 99%. It requirs a reboot at night to get the cpu to go back down. Show CPU shows the 1sec, 5sec, and 1 min averages. Show cpu slot shows 1% cpu use on all the slots. It never spikes over a gig of bandwidth over the 10gig uplink.
How can I see what individual processes are using the high CPU?
Thanks
Wyatt

Re: High CPU on procurve 5406

high cpu mainly cause network loop

you can enable spanning tree on 5400 switch


(config)#spanning-tree

in this way go to blocked state your loop port

you can see sh spanning-tree command blocked state loop port
