[jboss-jira] [JBoss JIRA] Commented: (JBAS-4939) Hudson JBoss-AS-5.0.x-TestSuite-sun15-noip testsuite run does not complete

[ http://jira.jboss.com/jira/browse/JBAS-4939?page=comments#action_12386314 ] Aleksandar Kostadinov commented on JBAS-4939: --------------------------------------------- Ok, I did some more investigation and have some conclusions. 1. The initial issue of JBoss not seeing its own sent mcast messages appears to be that dev90 needed a restart for unknown reason. 2. AFAICT there is no issue with the noip JBoss AS 5 hudson job. It fails but for other reasons. 3. The mcast receiver test is reliable. We were misleaded by it failing on RHEL 4U5 and above but clustering when one node is localhost and the other whatever IP works. Well taht works because of the linux mcast behavior when 2 processes join the same mcast group/port and on different interfaces. Effectively both receivers get mcast messages received through both interfaces. So in this situatuin one node listens to localhost, one to eth0 thus both seeing each other. Since this configuration is only a case when running the test suite we should not consider mcast receiver test unreliable. To see what I'm talking about do: a> start a reveiver on lo b> start a sender on lo c> send a message (will be received on RHEL 4U4 but not on RHEL 4U5 and above) d> start a receiver on eth0 e> send a message from the initial sender (will be received on both receiver ends) I think that's all about this issue.
