title: Java Heap Space error in glassfish
body: <p>I am using a fresh Glassfish install with very little customizations.</p>
  
  <p>I have a Message Driven Bean (ObjectUpdateMDB) that listens to a topic, then updates the object it receives in a database.  There are a lot of objects being updated.  After a while of running I get this exception:</p>

  <p>Looks like it is an issue with Heap Space.  What do I need to adjust the heap space for?  The App Server itself or the Broker?  How do I do this?</p>
