[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Dead Lock on a failover test

I got a dead lock during a testsuite run. I was doing some other stuff what may had made the behavior worse, but a dead lock shouldn't happen. It happened once during org.jboss.messaging.tests.integration.cluster.failover.FailoverExpiredMessageTest [junit] Found one Java-level deadlock: | [junit] ============================= | [junit] "Thread-6236": | [junit] waiting to lock monitor 0x00007fdcea027d10 (object 0x00007fdd25a50e28, a java.lang.Object), | [junit] which is held by "Thread-6235" | [junit] "Thread-6235": | [junit] waiting to lock monitor 0x00007fdcea027e00 (object 0x00007fdd25a5f790, a org.jboss.messaging.core.remoting.impl.invm.InVMConnection), | [junit] which is held by "Thread-6236" | [junit] | [junit] Java stack information for the threads listed above: | [junit] =================================================== | [junit] "Thread-6236": | [junit] at org.jboss.messaging.core.client.impl.ConnectionManagerImpl.failConnection(ConnectionManagerImpl.java:866) | [junit] -
