My first bet:

lsof |grep deleted


This will show open files that have been deleted.  The file system doesn't
actually unlink them until the file is not in use, whereas 'du' just goes
through a current directory listing (which doesn't include deleted files)

lsof should show you which user and PID is responsible, then you can restart
that program.

This might happen when deleting a log file while a process is still writing to it.

If that doesn't identify anything, you could look through lsof to find any open
files with a huge size.  That might indicate that a file was truncated while it
was being written to.
