Hi,

I have a simple request reply process in place, but am experiencing the following error,

Failed to write to reply queue queue://Q2LIVHA2
F1/WMQ01.0000.DMS01: MQJMS2008: failed to open MQ queue
javax.jms.ResourceAllocationException: MQJMS2008: failed to open MQ queue

It our tester is run, it works fine for the first 30 mins or so and then we fail to open the reply queue due to the above error. Does anyone know the cause of this error? Is it too many open connections??

I have checked the code and we lazy instantiate the reply queue, so we should reuse the same queue and not open a new one. We also resue the same JMSSession.

/**
* Lazy instantiated (thread safe) accessor for the JMS error queue
*
* @return Queue
*
*/
public synchronized Queue getJMSReplyQueue() throws JMSException, CorrespondenceException
{
if (m_replyQueue == null)
{
String queueURL = "queue://" + getMqProperties().get("queueManager") + "/" + getMqProperties().get("outputQueue");
m_replyQueue = getJMSSession().createQueue(queueURL);
}
return m_replyQueue;
}
