Please see http://nerdbynature.de/bits/2.6.39-rc4/oom/

- slabinfo-4.txt.bz2, contains /proc/sys/fs/{dentry,inode}-state and
/proc/fs/xfs/stat (is this interesting at all?) and a few other
/proc outputs
- messages-4.txt, contains the syslog from this run.

Should I enable a few more DEBUG_* options in the kernel? Which options
would be helpful?

Thanks for looking into it,
Christian.
