Hello,

We are running kernel-smp-2.4.21-15.EL currently (there is an upgrade to
this I have to do...)  This is a P4 system with hyperthreading turned
on, Asus P4P800 deluxe motherboard.

uname -a says:

Linux {FOO} 2.4.21-15.ELsmp #1 SMP Thu Apr 22 00:18:24 EDT 2004 i686
i686 i386


here is vmstat 1 for a few seconds

This system has been running for 50 days and the swap usage is at zero.
