[rabbitmq-discuss] Going crazy solving PRECONDITION_FAILED

Tue Feb 25 20:45:08 GMT 2014

How?  We're pulling our hair trying to get this resolve.  I don't see how
our app can execute the basicAck more than once considering I only
submitted one message to the queue and the consumer is only consuming that
one message.

We are only seeing this when we have created the second consumer
subscription.
