I just started seeing this too. I think I know what it is, and am trying to figure out how to go about fixing it. When someone closes their laptop or turns off their phone before closing the browser tab, it crashes the app. Something with socket.io + connect-mongo in DerbyJS, it's a new bug. Anyway, 500 indeed - but I'm using nodejitsu/forever-monitor to restart the app when it crashes, so it should come back just fine, you'll just have to refresh and wait a bit. Thanks for pointing this out
