1. If you aren't using clustering remove cluster-service.xml.
2. if you aren't using hypersonic remove hsqldb-default-service.xml (you may possibly have to fiddle with parts of jbossmq looking for NoTransDS)
hypersonic at one time caused bizarre hanging problems, but hasn't for a while. Cluster setup can take a long time and may hang under circumstances unknown to me (people have suggested DHCP servers causing problems, but others have no problem with them).
