After the jboss-ejb3-as-int:1.0.0-Beta9 upgrade the clustering tests we've started having issues with the clustering tests. I'm not sure if they are related: http://hudson.qa.jboss.com/hudson/view/JBoss%20AS/job/JBoss-AS-5.0.x-Test... [server:stop] Failed to shutdown server "cluster-udp-BR-1" before timeout. Destroying the process. ... [server:start] Failed to start server "cluster-tcp-1" before timeout. Destroying the process.
