      1. Start the AS with -Dorg.jboss.server.bootstrap.maxThreads=3
      You might have to use a higher number for maxThreads (set to 2 + number of persistence units with "hibernate.session_factory_name".)

      OR

      2. Remove "hibernate.session_factory_name" properties from the persistence.xml
      <property name="hibernate.session_factory_name" value="java:global/hibernate/SessionFactory"/>

      When deploying an EAR with two persistence units on single core machines, the server hangs.
      When increasing the number of cores to two, the same server just works.

      I traced the bug to the method in org.jboss.as.naming.WritableServiceBasedNamingStore.unbind
      The container attempts to register "hibernate/SessionFactory" twice.
      The first time it works, the second time it hangs on the wait statement.

      I suspect a race condition in the ServiceControllerImpl.
