CPU is more than 100% -> impossible
but top, mpstat, vmstat are ok
Version-Release number of selected component (if applicable):
Steps to Reproduce:
This is probably not a procps bug, but just the usual poor process accounting
that Linux does. However, that should show up in top too. When you say you don't
see it in top, do you mean the total cpu usage or in the actual process listings?
ps shows impossible CPU values. But with top, mpstat or vmstat I get correct CPU
This is a very clear ps bug
I forgot it. top shows _correct values_ in the total cpu usage _and_ in the
actual process listings.
Is this fixed by version 3.1.15 or later versions?
I will see it....
Upstream procps says that this is a kernel problem.
ok. I'm going to close it, now RHL is dead.
