Description of problem:

As seen in my logs:

22:53:50,559 ERROR [org.rhq.enterprise.server.discovery.DiscoveryServerServiceImpl] (http-/0.0.0.0:7080-366) Fatal error occurred during merging of inventory report from agent [Agent[id=0,name=app011,address=null,port=0,remote-endpoint=null,last-availability-ping=null,last-availability-report=null]].: javax.ejb.EJBTransactionRolledbackException: Transaction rolled back

What seems to happen is there is a database transaction for 'app011' that hangs, eventually aborts (after 10 minutes), and a secondary transaction that overlaps.

I'll update if I have more information.
