Same, here. 2.4.20-xfs and 2.4.21 (vanilla) both have some problem in kswapd. 
This happened after about 4 days and 6 hours of uptime/load. I use this box 
as a router with DHCP, DNS, NTP and SSH (for administration only.)

P100, 10GB HDD (ext3), 32MB RAM

I noticed the two oopses in syslog - see attachment.
