[rabbitmq-discuss] rabbitmq-c TTL setting not working for me - please help

[Kim Tran]

Simon,
Thanks for the hints.  I didn't have the basic.qos to receive one at a 
time. That's likely the reason.

So what would happen if I got all the messages straight away but slowly 
process them:  the queue would get bigger and bigger over time? and 
eventually crash with some socket error?

Thanks,
-Kim
