Hi, We are getting these exception in Clustered environment. For two servers in Cluster when 2nd Server starts we get this exception. We are using JAS 4.2.3 GA and JBM-1.4.0SP3. We dont know how to fix it. Both the server are using different & unique ServerPeerID. This is happening in 2nd Server start up | 2008-12-30 21:59:47,984 DEBUG [org.jboss.jms.server.destination.QueueService] Starting jboss.messaging.destination:service=Queue,name=batchAuditQueue | 2008-12-30 21:59:48,000 ERROR [org.jboss.messaging.util.ExceptionUtil] Queue[null, name=batchAuditQueue] startService | java.lang.IllegalStateException: Channel id map for node 1307 already contains binding for queue 12 | at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.addBindingInMemory(MessagingPostOffice.java:2375) | at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.internalAddBinding(MessagingPostOffice.java:1863) | at org.jboss.messaging.core.impl.postoffice.MessagingPostOffice.addBinding(MessagingPostOffice.java:444) | at org.jboss.jms.server.destination.QueueService.startService(QueueService.java:110) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) | at org.jboss.system.ServiceMBeanSupport.start(ServiceMBeanSupport.java:196) | at sun.reflect.GeneratedMethodAccessor74.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:133) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterceptor.java:142) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | Awaiting response.
