sar -k -q

After running sar -M -q the
%runocc shows at 100% and the
runq-sz can run anywhere between
1.0 to 4.2. When the runq-sz gets to 3.1 %runocc goes to 100%
which is OK but runocc stays at
100% no matter what. We are unable to find why. Any body
have an idea? We have rebooted the system but that did not work

Re: sar -k -q

If the runq is 2-3 on a single cpu server system and youve got %runocc always at 100 then your out of cpu. either this is a *feature* of the application you are running or else you have a runaway process that needs killing. Use top to see if you can identify the process hogging most of the cpu, if you can, kill it or restart it. Or else you may need to recycle your server to clean everything up.
If you want truly to understand something, try to change it. (Kurt Lewin)

Re: sar -k -q

The system has been recycled.
The problem began when a person
unplugged the system while it was
running. From that time on we have been receiving the 100%
