[rabbitmq-discuss] reply-code=406, reply-text=PRECONDITION_FAILED - unknown delivery tag

[Vineet Chadha]

Hello,

We are using rabbit cluster for a few months now and things have been
working fine until now.

ENVIORNMENT
=============
RabbitMQ Server version 2.8.2
RabbitMQ Client 2.7.1

One of our applications is consuming messages from RabbitMQ server over WAN.
This was a recent introduction i.e. going over WAN to a diff. RabbitMQ
cluster than the local one.
After a few hours of being up and consuming messages, one of the many
channels in the application
is closed by the server with the following message.

{#method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED -
unknown delivery tag 1073743883, class-id=60, method-id=80), null,
"[B at 607daec3"}
