So all this sounds like the messages are being sent to your application:

no_ack = 1 -> messages are sent to your app, RabbitMQ forgets about them 

no_ack = 0 -> messages are sent to your app, RabbitMQ treats them as 
unacknowledged until you ack.

The source code you posted doesn't show any code that actually handles 
received message frames - you do have some right?

Can you post your whole source somewhere? It's quite difficult to tell 
what is going on looking at fragments.
