Creation of Durable Subscriber in IBM MQ fails

Using IBM MQ 6.0\. Generic RA is deployed in the application server and a web
application is also deployed. The EJB in the application creates a durable
subscriber. The appropriate topic connection factory and topics are defined in
IBM MQ.

The following code throws an exception sometimes -
createDurableSubscriber(topic, "genra15")

where 'genra15' is the client id value. The same is specified while creating the
topic connection factory in IBM MQ.

The code was working fine. When it failed I decreased the length of the client
id value. It passed initially and then started failing again.

The error message is :

javax.enterprise.system.stream.err|_ThreadID=19;|com.ibm.mq.jms.BrokerCommandFailedException:

Seems to be an IBM MQ issue -
