ReceiveNoWait returns null but many there are 5000 messages!

Hi, I dont know much about client message cache so maybe this question is a newby question.


I have a client that is polling a jms queue with receivenowait method. The client proceses 10 max messages per transaction.

The problem is that the queue has about 5000 messages and the client only proceses one message per tx.

This behaviour appears sometimes and not necesarily under heavy load.

Any clue? Is this normal? Is this tunable?

Thanks.

Unanswerable question.

I am sorry. I will give some environment information:

We are using JBoss 4.0.1.sp1 in the default server configuration.
The OS y es Linux Redhat 9.
The JMS server is using UIL2 Invocation Layer and using Oracle 9i to persist jms messages.
