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:

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.
