If you change the conf/jboss-service.xml to 4446 the conflict is gone; no need to change cluster-service.xml. I don't have the binary download for 4.2.2.GA on hand, just the source code (which is identical to the SVN tag for that release). In the source (and in a build from that source) the jboss.remoting:service=Connector,transport=socket serverBindPort value is 4446. Suggest you compare your conf/jboss-service.xml file with one from an unaltered 4.2.2.GA download and look for any other differences. IIRC, 4448 was used for jboss.remoting:service=Connector,transport=socket serverBindPort in some earlier releases. It's possible I'm wrong.
