I found that the clustering tests would fail to start due to OOM. The start-jboss macro in testsuite/imports/server-config.xml only gives 64M to the AS by default, which is no longer enough to start the server. I expect other tests that use the AS are failing for the same reason. For the clustering tests, I found modifying the tests-clustering-startup target so start-jboss looked like the following let them run: <start-jboss conf="node0" host="${node0}" jvmargs="-Xmx128M"/> I've checked in build-test.xml with that applied to all the start-jboss calls. I don't know if that will resolve all issues, but it's something. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3998032#...
