Hi all,

We are using Redhat (2.6.9-11.ELsmp). Our Top command currently looks like this:

top - 15:30:50 up 4 days, 7:57, 1 user, load average: 14.07, 15.58, 14.87
Tasks: 55 total, 2 running, 53 sleeping, 0 stopped, 0 zombie
Cpu(s): 97.0% us, 2.3% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.7% si
Mem: 8310724k total, 5086956k used, 3223768k free, 145248k buffers
Swap: 1020088k total, 0k used, 1020088k free, 2525472k cached


Brutal.

But we can't find out WHICH processes are eating CPU. Every single one of the the processes listed below shows 0% CPU. ALL of them. Even when sorting by CPU usage with 'P'

any form of "ps" command shows ALL processes with 0%CPU.

Has anyone seen anything like this?

We are stumped. We need to find out WHICH processes are eating CPU but are coming up empty.

We aren't running VMWARE or any virtualization. It's a dual core DELL poweredge system, and the only big app on it is mysql.

Sampling is always "hit and miss". Try htop - or else collectl.
