NullPointerException in message queue!!!

I'm using Sun Message Queue 3 3005Q4. I get the following error in one of the queues. The message size and no of messages is evrything in limit. Can anyone tell what this error is about?

[14/Aug/2006:02:54:04 EDT] Internal Error Unable to consume [consumer:0, type=CLIENT_ACKNOWLEDGE]:null:

Thanks

My interpretation of that errors is that the acknowledgement mode is null.

Could it be that you did not specify an acknowledgment mode? i.e:

subTopic = BusObjectStore.getTopic(jndiTopicName);

ts = tc.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);

tsub = ts.createSubscriber(subTopic);

But I use the same jndi code for accessing several other queues. All the queues work fine except this one that throws up an exception.Thanks.

I am not refering to the JNDI part; do you explicitly create a session with something like:

ts = tc.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);

?

That is all I can think of.
