You seem to be talking about publisher confirms *and* delivery acks at the same time. Do you actually use both?
They are *not* related to each other.

Have you tried running protocol tracer [1] or Wireshark to see what’s coming down the wire?
The issue you are seeing can be an unsynchronized concurrent updates issue. Inspecting
protocol methods will make it clear what RabbitMQ sends.
