Failback of standalone JMS client fails with http connector ----------------------------------------------------------- Key: WFLY-5456 URL: https://issues.jboss.org/browse/WFLY-5456 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 10.0.0.CR2 Reporter: Miroslav Novak Assignee: Clebert Suconic Priority: Critical Attachments: log.txt, servers.zip, standalone-full-ha-1.xml, standalone-full-ha-2.xml Failback of standalone JMS client fails if http connector is used. There are 2 EAP 7.0.0.DR11 (Artemis 1.1.0) servers configured in dedicated topology with shared store. If live server is killed (clients failover) and then restarted (so failback occurs) then sometimes client does not failback to live server. From the thread dump of one client it seems that it's stuck on: {code} Stack trace of thread: Thread[Thread-16,5,main] Stack trace of thread: Thread[Thread-2 (ActiveMQ-client-global-threads-1995983824),5,ActiveMQ-client-global-threads-1995983824] ---sun.misc.Unsafe.park(Native Method) ---java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:215) ---java.util.concurrent.locks.AbstractQueuedSynchronizer.doAcquireSharedNanos(AbstractQueuedSynchronizer.java:1037) ---java.util.concurrent.locks.AbstractQueuedSynchronizer.tryAcquireSharedNanos(AbstractQueuedSynchronizer.java:1328) ---java.util.concurrent.CountDownLatch.await(CountDownLatch.java:277) ---org.apache.activemq.artemis.core.protocol.core.impl.ActiveMQClientProtocolManager.waitOnLatch(ActiveMQClientProtocolManager.java:130) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.getConnectionWithRetry(ClientSessionFactoryImpl.java:770) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.reconnectSessions(ClientSessionFactoryImpl.java:694) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.failoverOrReconnect(ClientSessionFactoryImpl.java:558) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.handleConnectionFailure(ClientSessionFactoryImpl.java:461) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl.access$400(ClientSessionFactoryImpl.java:68) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl$DelegatingFailureListener.connectionFailed(ClientSessionFactoryImpl.java:1120) ---org.apache.activemq.artemis.spi.core.protocol.AbstractRemotingConnection.callFailureListeners(AbstractRemotingConnection.java:57) ---org.apache.activemq.artemis.core.protocol.core.impl.RemotingConnectionImpl.fail(RemotingConnectionImpl.java:204) ---org.apache.activemq.artemis.spi.core.protocol.AbstractRemotingConnection.fail(AbstractRemotingConnection.java:179) ---org.apache.activemq.artemis.core.client.impl.ClientSessionFactoryImpl$CloseRunnable.run(ClientSessionFactoryImpl.java:946) ---org.apache.activemq.artemis.utils.OrderedExecutorFactory$OrderedExecutor$1.run(OrderedExecutorFactory.java:94) ---java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) ---java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) ---java.lang.Thread.run(Thread.java:745) {code} See attached log.txt for more details.
