Standalone JMS client of 2 node colocated live/backup symmetrical cluster fails to failover. -------------------------------------------------------------------------------------------- Key: WFLY-6486 URL: https://issues.jboss.org/browse/WFLY-6486 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 10.0.0.Final Environment: 2 node symmetrical colocated live/backup cluster (domain mode). Configuration (domain.xml, host-master.xml, host-slave.xml) provided as attachment. Reporter: Michal Sudra Assignee: Jeff Mesnil Attachments: client.log, domain.xml, host-master.xml, host-slave.xml, JmsClusterFailoverTest.java, master.log, slave.log There are two WildFly 10.0.0.Final servers configured in colocated replication topology running in domain mode and a standalone JMS client connected. When I kill one of my Wildfly instance, I can see in the logs that the backup server becomes live in the second server. But the client receives this error : {noformat} 2016-04-04 16:32:45,417 DEBUG [org.jboss.naming.remote.protocol.v1.RemoteNamingStoreV1] (Remoting "config-based-naming-client-endpoint" task-9) Channel end notification received, closing channel Channel ID 8baa48f5 (outbound) of Remoting connection 75986426 to /192.168.99.102:8080 2016-04-04 16:32:45,456 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Trying reconnection attempt 0/-1 2016-04-04 16:32:45,457 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Trying to connect with connector = org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory@64f6106c, parameters = {httpUpgradeEnabled=true, port=8080, httpPpgradeEndpoint=http-acceptor, host=192.168.99.102} connector = null 2016-04-04 16:32:45,458 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Started Netty Connector version 4.0.30.Final 2016-04-04 16:32:45,458 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Remote destination: /192.168.99.102:8080 2016-04-04 16:32:46,474 ERROR [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) AMQ214016: Failed to create netty connection java.net.SocketException: Network is unreachable: no further information: /192.168.99.102:8080 at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) at io.netty.channel.socket.nio.NioSocketChannel.doFinishConnect(NioSocketChannel.java:224) at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe.finishConnect(AbstractNioChannel.java:289) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:528) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:468) at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:382) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:354) at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:110) at java.lang.Thread.run(Thread.java:745) 2016-04-04 16:32:46,478 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Connector towards NettyConnector [host=192.168.99.102, port=8080, httpEnabled=false, httpUpgradeEnabled=true, useServlet=false, servletPath=/messaging/ActiveMQServlet, sslEnabled=false, useNio=true] failed 2016-04-04 16:32:46,480 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Trying backup config = TransportConfiguration(name=http-connector, factory=org-apache-activemq-artemis-core-remoting-impl-netty-NettyConnectorFactory) ?httpUpgradeEnabled=true&httpPpgradeEndpoint=http-acceptor&port=8180&host=192-168-99-101 2016-04-04 16:32:46,480 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Started Netty Connector version 4.0.30.Final 2016-04-04 16:32:46,480 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Remote destination: /192.168.99.101:8180 2016-04-04 16:32:47,495 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Connector towards NettyConnector [host=192.168.99.101, port=8180, httpEnabled=false, httpUpgradeEnabled=true, useServlet=false, servletPath=/messaging/ActiveMQServlet, sslEnabled=false, useNio=true] failed 2016-04-04 16:32:47,499 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Started Netty Connector version 4.0.30.Final 2016-04-04 16:32:47,499 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Remote destination: /192.168.99.101:8180 2016-04-04 16:32:48,524 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Connector towards NettyConnector [host=192.168.99.101, port=8180, httpEnabled=false, httpUpgradeEnabled=true, useServlet=false, servletPath=/messaging/ActiveMQServlet, sslEnabled=false, useNio=true] failed 2016-04-04 16:32:48,526 DEBUG [org.apache.activemq.artemis.core.client] (Thread-6 (ActiveMQ-client-global-threads-1863167529)) Backup is not active. {noformat} and does not failover to the second server.
