Unless you have a fairly unusual setup (swapping into a file in /usr),
/usr being full has nothing to do with swap being full.  You can check
swap usage with "swapinfo".  There's no simple way to identify how much
swap space is being used by each process but VSZ reported by 'ps -axl'
might suggest the culprit(s) - a few excessively large processes or an
excessive number of small ones.
