I think the server it's running on has 1.8.5.  Thanks to everyone for 
the responses, those articles were definitely interesting.  I did some 
quick calculations based on which objects I know are persisting and I 
think it's actually using about 900kb per day of ram so manually 
activating GC wouldn't help much.  I redesigned the core of the app and 
the next version isn't going to have nearly as much state so that won't 
be a problem any more when I deploy it next week.
