There are no entries in any log for oom killer that I can see. Hmmm. I'm running the latest Ubuntu LTS with 2.6.24-19-server kernel. Just ran the latest apt-get upgrade and only was missing an update to pciutils. btw, here's the output of free: total used free shared buffers cached Mem: 33080292 32983004 97288 0 87992 24882632 -/+ buffers/cache: 8012380 25067912 Swap: 7815580 144 7815436 Interesting thing, I've got a machine with the same configuration sitting next to it that's not doing this. But it seems odd it could be hardware induced.
