If you're on 8.1 it's important to be on the latest 8.1 -- there are
at least 17 significant bugs that warranted bug-fix releases between
8.1.3 and 8.1.20 including security bugs and data corruption bugs.

Ugh, then it sounds like there's a real as-yet unidentified problem.

The other thing to check before panicking is, has this server ever run
with fsync off and crashed (either kernel panic or power failure)?

What does the storage system on this server look like? Are they IDE or
SCSI drives? Is there an LVM layer involved? etc.
