Adam,
Did you try to use EJB Timers and let the EJB container do the job of calling
your beans every 20 minutes?

On the web tier we have a couple of timers (java.util.Timers) that are started by context listeners, that every 20 minutes call an EJB to see if reports need to be generated and made available to the web users. Because of some bugs in glassfish with injecting ejbs in this scenario, we look them up using a remote initial context each time the timer runs...which works fine for about an hour and a half, then everything goes crazy. Every call to an ejb gives a time out, and our entire application stops working. There is nothing of note in the ejb server logs that I can see (definitely no errors anyway), but in the web tier logs we get the following:
