[rabbitmq-discuss] Going crazy solving PRECONDITION_FAILED

Tue Feb 25 19:44:53 GMT 2014

I don't understand how this is possible.  I submitted one message to a
queue.  It should execute a downstream service for that queue.  The other
consumer subscription is subscribing to a different queue.  So, it's hard
to understand how it's "double ack/reject" on the same delivery.
