Does the problem relate to

org/apache/qpid/jms/FailoverPolicy.java

    public FailoverPolicy(ConnectionURL connectionDetails, AMQConnection 
conn)
    {
        FailoverMethod method;

        // todo This should be integrated in to the connection url when it 
supports
        // multiple strategies.

        _methodsRetries = 0; <<< change this value to a very large number, 
999
