Some further test: I also tried to kill instance A, so a local instance. Then also C is influenced once. After my 50s retrytime the bridge to C is back again. (no, C is not the problem. It also happes the other way round) After restarting instance A the connection from X to A is reestablished but then it failed 2 time again with messages like the example above. Between the reconnect and disconnect it always took around 3 seconds: | 09:44:41,421 INFO [Bridge] jboss.messaging:name=OutgoingBridge_AEOSA,service=Bridge Succeeded in reconnecting to servers | 09:44:44,437 WARN [Bridge] jboss.messaging:name=OutgoingBridge_AEOSA,service=Bridge Detected failure on connection | javax.jms.JMSException: Failure on underlying remoting connection | at org.jboss.jms.client.remoting.ConsolidatedRemotingConnectionListener.handleConnectionException(ConsolidatedRemotingConnectionListener.java:102) | at org.jboss.remoting.ConnectionValidator$1.run(ConnectionValidator.java:641) | 09:44:44,484 ERROR [ClosedInterceptor] ClosedInterceptor.ClientSessionDelegate[c7-xv1z6xrf-1-k6dr6xrf-d1wvvl-2227p4]: method getXAResource() did not go through, the interceptor is CLOSED | 09:44:44,484 WARN [loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.rollbackxaerror] [com.arjuna.ats.internal.jta.resources.arjunacore.rollbackxaerror] XAResourceRecord.rollback - xa error XAException.XAER_NOTA | 09:44:44,484 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_54] - Top-level abort of action -5601fdfe:82d:49af8f92:ea received TwoPhaseOutcome.FINISH_ERROR from <ClassName:RecordType.JTA_RECORD> | 09:44:44,484 WARN [loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.rollbackxaerror] [com.arjuna.ats.internal.jta.resources.arjunacore.rollbackxaerror] XAResourceRecord.rollback - xa error XAException.XAER_NOTA | 09:44:44,484 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_54] - Top-level abort of action -5601fdfe:82d:49af8f92:ea received TwoPhaseOutcome.FINISH_ERROR from <ClassName:RecordType.JTA_RECORD> | 09:44:44,484 WARN [Bridge] jboss.messaging:name=OutgoingBridge_AEOSA,service=Bridge Will retry after a pause of 50000 ms | 09:45:34,609 INFO [Bridge] jboss.messaging:name=OutgoingBridge_AEOSA,service=Bridge Succeeded in reconnecting to servers | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4215139#...
