Cause

An error caused by routing a message to a queue should not be propagated to the producer because it's a basic feature of a message broker to decouple the publisher from the consumer (the queue). This was not the case here.

Resolution

when a client consumed from an unavailable quorum queue, the following crash occurred:

{badmatch,{error,noproc}}
[{rabbit_quorum_queue,consume,3,[{file,\"rabbit_quorum_queue.erl\"},{line,993}]}

 

This fixes the bug by returning an error when registering a quorum queue consumer to rabbit_queue_type.

This will be fixed in 4.1 released mid April 2025
