ActiveMQ 5.5 sending message twice

Hi,


We are facing an issue with ActiveMQ version 5.5 for stomp clients.
The issue is, we have a python client using stomp, which uses transactions.
Whenever there is new message, ActiveMQ tries to send two messages, and message count is negative.
There is no exception in python side, and it does its job correctly.

Am I missing something?

Thanks

seems like that would be easy to prove with a simple junit test.

see: org.apache.activemq.transport.stomp.StompTest in activemq-core

Hi,

Upon some investigation I found that, stomp client uses transactions.
And when it sends ack message, message count decreases by one, and again when "commit" is sent, message count further decreases
and becomes negative.

What could be the problem? Please reply as we have system in production :-(.

Thanks
