I have looked that one.. it is https://jira.jboss.org/jira/browse/JBMESSAGING-1558. Right now, the testsuite fails very frequently on failover tests in my box... with or without my changes. But it frequently pass if I run only the failover tests. There is some leak somewhere probably. I suspect (pure guess) about those *FileStorageTest as the failover tests will run after those. I will run the failover tests with a big number of iterations to make sure I'm not creating any failures. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4224906#...
