http://community.jboss.org/message/518812#518812 Author : Krystian Siuda Profile : http://community.jboss.org/people/ksiuda Message: -------------------------------------------------------------- Hi, I'm crashtests of an JBoss cluster dedicated to be an JMS server. I wrote an simple (2 threaded) JMS client that connects to the server and simultaneously sends&receives uniq messages checking whether they are duplicated/lost etc... The scenario I'm currently stuck with is: - i put 2 server nodes up - i start the client (mentioned before) - i see the traffic - kill (sig kill) the 1st node - i still see the traffic after failover - kill (sig kill) the 2nd node - the traffic stops - after some time client starts to throw exceptions like: javax.jms.IllegalStateException: The object is closed at org.jboss.jms.client.container.ClosedInterceptor.invoke(ClosedInterceptor.java:157) at org.jboss.aop.advice.PerInstanceInterceptor.invoke(PerInstanceInterceptor.java:86) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) at org.jboss.jms.client.delegate.ClientConsumerDelegate.receive(ClientConsumerDelegate.java) at org.jboss.jms.client.JBossMessageConsumer.receive(JBossMessageConsumer.java:86) at auto.Main.receive(Main.java:92) at auto.Main.receiveWrap(Main.java:138) at auto.Main$2.run(Main.java:195) at java.lang.Thread.run(Thread.java:619) - and after some more time: javax.jms.JMSException: Maximum number of failover attempts exceeded.

I'm using: Java JRE 6 (build 1.6.0_17-b04) JBossMessaging 1.4.3.GA JBoss 5.1.0.GA The client is ussing port 1099 to lookup the JNDI (is this significant?). The client code is extended version of this: http://pastebin.com/m410ce7d0 (the connection is created and maintainted in the very same way as in this example) Is it an configuration issue or jboss error? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/518812#518812
