> Wrote a Java program to send 100000 TextMessage's to a JMS queue.  An EJB3 MDB in JBoss is listening to the queue and does a System.out.println when messages are received.
> After ~25k messages are processed by the MDB, the following message is printed to the screen, and messages stop being processed by the MDB:
> 16:57:33,391 INFO  [KahaStore] Kaha Store using data directory activemq-data/jboss.activemq/tmp_storage
> It appears activemq is hanging just after the "KahaStore" message is output.  No such problems have been observed using JBossMQ.
> Attached is the output of kill -3 <pid of jboss> showing stack traces of all threads just after the hang happens (dump.txt), the client program that sends lots of messages (Test.java), and the MDB (TerminalTrackConsumerMDB.java).
