I've run the ejb3 4.2 testsuite with -Dnode0=IP1 -Dnode1=IP2 where IP1 is not localhost. There are some tests failing with "Retries exceeded, couldn't reconnect to 127.0.0.1:####". testGetEJBHome from IiopRemoteUnitTestCase is one of them. See attachment for more tests and trace. You can't see these tests failing on http://cruisecontrol.jboss.com/cc/buildresults/ejb3-4.2-testsuite because there node0 is localhost. For the above mentioned testcase I see in ejb3/src/test/org/jboss/ejb3/test/iiop/unit/IiopRemoteUnitTestCase.java 'props.put("java.naming.provider.url", "corbaloc::localhost:3528/NameService");'. Instead of localhost there has to be used the node0 property. I guess the other tests with same errors have the same problem.
