Subject [jira] [Commented] (AMQ-3375) stomp consumer might not receive all msgs of a queue
Date Wed, 29 Jun 2011 18:30:28 GMT


Timothy Bish commented on AMQ-3375:

A reliable way to make this test case always pass is to add the receipt request header to
the final produced message and do a receive to await the response, this will ensure that all
messages are read by the broker and placed on the queue.

>         Environment: stomp consumer on virtual destination

> Have a testcase that connects a Java stomp consumer to a virtual destination queue and
consumes a fixed amount of msgs.
> During the test I noticed that the consumer does not always receive the full amount of
> Instead the receive times out although JMX QueueSize property is greater than 0. However
when trying to browse the queue using JMX, it returns null, despite the fact that not all
msgs got dequeued yet (dispatch and dequeue counter < enqueue counter).
> So far I reproduced this with a stomp producer/consumer only. The producer writes msgs
to a virtual topic VirtualTopic.Foo and the consumer takes msgs off the Consumer.A.VirtualTopic.Foo
queue. Using JMX I noticed all msgs got moved from the virtual topic to the queue (reflected
by JMX enqueue counter) but not all msgs got consumed.
> So it seems the broker lost some msgs on the way.
