That's someone's guess.  The reality is that the fileserver does not 
actually add up the space used by files in a volume, ever.  It keeps a 
counter in the volume header, which is adjusted as files are created and 
removed.  If something happens which causes damage that then has to be 
repaired, fsck removes a file, a file somehow becomes orphaned, etc, then 
the quota can become different from actual usage.
