Yes, I've seen stuff like that before.  I've usually ended up tracking it
down to either a well-intentioned student script that is doing some while
(1) equivalent in conjunction with file access, often on multiple
machines, or a piece of badly written vendor software (yes, I know that's
redundant) that doesn't understand the concept of permission denied and
goes into a tight loop constantly retrying whatever disk write it was
trying to do.

The latter problem is depressingly common; I've seen a huge variety of
commercial mathematical and statistical packages go insane if a token
expires out from under them.
