Ok, but that does not sound like deadlock.

Yes: messages may be removed from a queue if the queue was declared with
TTL: http://www.rabbitmq.com/ttl.html#per-queue-message-ttl

I'm afraid you have not provided enough information for me to
investigate any further. If you can reproduce the problem then please
provide a description of the steps to reproduce, or a minimal
self-contained piece of code that triggers the failure. In the meantime
here are some suggestions:

- v2.7.1 is very old now. Upgrade to the latest version
- Try not to use polling
