Well, if this is a publicly available system, there is always the chance
that your server has been compromised and is hosting warez or other junk.

If this isn't a critically busy system, you could go into single user
mode and run "e2fsck -f <dev>" to see if there is something wrong with
the filesystem.  However, I suspect that as soon as you shut down to
single user mode and your processes are killed that your space will
become available again even before e2fsck is run.
