Weblogic.messaging.dispatcher.DispatcherException!!??

Question

Hi,
I have the following piece of code extract which creates a JMS Session. I am looking up a queue from a WLS1032 to a WLS1033 (SOA Suite 11g) and publish messages to it.
if (remoteCtx == null || remoteJmsConnection == null || remoteQueue == null) {
     setupRemoteJMSResources();
session = remoteJmsConnection.createSession(false, Session.AUTO_ACKNOWLEDGE);
sender = session.createProducer(remoteQueue);
private void setupRemoteJMSResources() throws NamingException, JMSException {
          Hashtable<String, String> env = new Hashtable<String, String>();
          env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
          env.put(Context.PROVIDER_URL, soaProviderUrl);
          env.put(Context.SECURITY_PRINCIPAL, username);
          env.put(Context.SECURITY_CREDENTIALS, password);
          remoteCtx = new InitialContext(env);
          QueueConnectionFactory connectionFactory = (QueueConnectionFactory) remoteCtx.lookup(jmsRemoteCFName);
          remoteJmsConnection = connectionFactory.createQueueConnection();
          remoteQueue = (Queue) remoteCtx.lookup(remoteQueueName);
It has been working fine the last month but yesterday started to throw the following exception at the createSession() line.
I cannot find the cause of this exception and I would like to prevent it in the future. It is running on a WLS1032 in a SLSB.
Could anybody provide a hint of what could have caused this? Start/Stop of the application resolved the problem but I would like to further investigate it.

Check the soa_prod_a1:soa_a2 logs during the timestamp Oct 21, 2014 5:55:54 PM  issue occured.
The below error message tells us the remote JVM is down and inaccessible.
java.rmi.ConnectException: This RJVM has already been shutdown
Check if the below port numbers are listening on the below ipaddresses
