JBM 1.4.0 SP3 JBoss 4.2.2 GA JDK 1.5.0_06 RedHat Linux I am getting the following error multiple times in a load test I am running. It does not happen on every message being processed but on most of them. ERROR [org.jboss.jms.client.container.ClosedInterceptor] ClosedInterceptor.ClientSessionDelegate[249]: method createMapMessage() did not go through, the interceptor is CLOSED. The createMapMessage() method is being called on the QueueSession class. There are also NullPointerExceptions happening sometimes in the call to QueueSession.createMapMessage() which tells me that the QueueSession is null for some messages (but not for others). I am also running into memory issues after a few hours into the test. If anyone has any ideas it will be greatly appreciated.
