It happened at least 2-3 times in 2008, last time being around september (not
related to the server load).

The 2 volumes shutting down have some things in common: they contain a large
number of files (I don't know if 2-5 million files - not in the same dir - is
"large" or "huge" to handle for that kind of FS), and they have directories with
20000+ files and long filenames (40 characters). On the other hand, I have a
mail archive containing very big Maildir directories (XFS, 10k+ files, long
filenames) without a single problem on it.

BTW, all the XFS volumes are all created with a big log size (-l size=128m) and
mounted with big log buffers (logbufs=8).

Is there some changes in the XFS current kernel code since 2.6.21.5 that could
be worth trying? Note this is a production file server that cannot be easily
upgraded.
