Comment 1 Alexander Larsson 2003-09-25 04:58:53 EDT

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?

Comment 2 acount closed by user 2003-09-25 17:42:34 EDT

ps shows impossible CPU values. But with top, mpstat or vmstat I get correct CPU
values.

This is a very clear ps bug

Comment 3 acount closed by user 2003-09-25 19:46:23 EDT

I forgot it. top shows _correct values_ in the total cpu usage _and_ in the
actual process listings.

Comment 4 Daniel Walsh 2004-03-28 21:27:42 EST

Is this fixed by version 3.1.15 or later versions?

Comment 5 acount closed by user 2004-04-02 16:40:09 EST

I will see it....

Comment 6 Daniel Walsh 2004-05-28 13:50:36 EDT

Upstream procps says that this is a kernel problem.

Comment 7 acount closed by user 2004-06-10 05:18:50 EDT

ok. I'm going to close it, now RHL is dead.

-thanks-
