> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.3.0
> Environment: Windows XP Professional 2002, Service Pack 2, Intel Pentium D 3ghz, various 1.5 and 1.6 versions of jdk

> I have written a test case which will demonstrate the following scenarios:
> 1. Simple producer driving a queue, simple consumer pulling from the queue.
> 2. Simple producer driving a queue, simple consumer pulling from the queue and producing an echo of the original message into the same queue.
> Expected: message delivery should not be interrupted.
> Actual: in scenario 2, eventually (about 500k messages in my environment), the delivery is halted to the consumer.
> Test Output:
> waiting for consumer to pause ... consumer: 0, producer: 0
> waiting for consumer to pause ... consumer: 3738, producer: 29796
> waiting for consumer to pause ... consumer: 9224, producer: 67841
> waiting for consumer to pause ... consumer: 9224, producer: 67841
> waiting for consumer to pause ... consumer: 9224, producer: 67841
> waiting for consumer to pause ... consumer: 9224, producer: 67841
> waiting for consumer to pause ... consumer: 9224, producer: 67841
