In the same user's account, eh?

Speaking from rsync experience, if a *nix partition becomes completely
full, you do get an immediate NO SPACE error on a write() and rsync
reports it.

But since all the problems were associated with a particular user,
perhaps it is a quota issue, and write() calls in that case might
not return an error (which would be unfortunate...).

Dan - can you check that user's quota?
