Hmm, having the same problem, this is my system:

uptime:
10:06pm up 19 days, 19:28, 1 user, load average: 0.00, 0.00, 0.00

ps -lx:
40 0 3 1 -12 -12 0 0 120af9 SW< ? 71224877:53 (kswapd)

uname -a:
Linux server.ds9a.tudelft.nl 2.0.33 #4 Thu Jan 8 15:22:54 CET 1998 i486

This also is a 486 with 8 Mb, quite swappy:

grep swap </proc/stat:
swap 625855 143408

Notice the CPU-time for kswapd is the same; I can't find the .config, I
could make some wild guesses:
IDE floppy, HD, ppp, slip, IP-forwarding, IP-masquerading, NE2000 driver,
don't know about RST/SYN-cookies.

AFIAK it's running a plain 2.0.33; maybe I should compile 2.0.34pre2 or wait
for 2.0.34 - I consider this machine "production", just because I have to
descend 1 flight of stairs to get physical access and would like it to be
zero-maintenance.

What does this server do? It's (a) our home dialup-server, and (b) our home
mail-relay host. What's connected to the ethernet are other 2 PC's and a
Sparc, all running Linux (2.{0,1}.x)

Btw, this server is running Redhat 4.1, maybe they included a faulty kswapd?

Some mm people know what's going on?
