Hehe, no. It's got 32 Gig of ram and is using 25G of that for kernel
cache. 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.
