No, I meant Red Hat's kernel 2.4.20-54. It's based on 2.4.21-pre4
with patches from Alan Cox, Arjan van den Ven and several
other people from RedHat.

OK, I have downloaded procps 3.1.6 and have retested this on
both 2.4.20-2.54 (2.4), 2.5.63 (stock) and 2.5.63-mm1. I have attached
to this message "top -d1 -b" and "vmstat 1" command outputs,
compressed with bzip2 to shorten the message length. I hope they
will help in clarifying things a little. Both command were started up a
while before clicking "Reply" and a few seconds after the message
window opened up, just to let the system stabilize.

A little bit more about my scenario: I'm running Red Hat Phoebe Beta 3
(what will in fact turn 8.1) with glibc-2.3.1, Evolution 1.2.2, XFree86 4.3.0
and KDE 3.1. I think Evolution has been compiled against glibc-2.3.1 and
so it will be using NPTL. As for XFree86 and KDE, I compiled them myself
and I'm sure they are using glibc-2.3.1 and NPTL.
Please, dont' hesitate in contacting me for further investigations.
Thanks!
Felipe Alfaro
