I agree - a non root userland process should definitely not affect the
filesystem. I mentioned it only because it may be a reason for a
non-expected pattern of fs operations.

That was the dmesg output - not much goes to logs, as they're on /var,
which was the affected filesystem. Things I've seen suggest that this
error can certainly be caused by a hardware problem, but the disk is a
hardware RAID5 array on an ICP controller, which maintains it's own
hardware log of disk problems. I've seen no sign of any problems with
the array, and the controller doesn't show anything that could have
presented an error to the OS layer, so I'm inclined to doubt the
"hardware error" theory at the moment.
