How often were you calling sync()? Your configured queue depth is quite 
large so you shouldn't need to do it that often.

However if you really don't want to do that then you can simply flush() 
and then keep track of incomplete transfers and ensure that the number 
of those does not get too high (the messaging API does this for you).

Alternatively you can build in some feedback from consumers, e.g. by 
having them respond to a reply-to address every N messages. That way you 
can track the queue depth even more directly.
