[rabbitmq-discuss] [2.4.0] random message loss with Stomp and topics?

[Michael Justin]

Hello,

Below is a Stomp log for a successful test case which uses a Topic 
destination and two subscribers:

* two different Stomp client connections subscribe to a topic (Stomp 
header frame: "destination:/topic/TestTopic")
* the third Stomp client connection sends two messages to this topic
* the two subscribed clients await the messages

However, the tests show many cases where the broker does not deliver all 
messages to both clients. After the first message, one / two /three 
remaining message are received or not.

Maybe there is an error in the Stomp headers of my client for the send 
or subscribe frames?

All other unit tests - with Queue destinations - pass with 100% success.

I will also try to debug it server-side using the management plugin.
