Issue
In my setup where I have numerous consumers on explicitly defined queues (e.g. `queue.eventA.send, `queue.eventB.send`). These queues are auto-created and also have auto-delete turned on. Recently I added a wildcard consumer on `queue.*.send`, and noticed that after restarts of part of my applications, I occasionally get a consumer that should be consuming on the specific queues
(e.g. `queue.eventA.send`) suddenly starts consuming from `queue.*.send` instead, giving that queue 2 consumers instead of the expected 1.
Reproduction
I'm able to consistently reproduce the issue, but it's difficult to share as it relies on some Docker containers with my applications. High-over, it should be easily reproducible in a testcase as well:
- Start a clean environment that initializes the following consumers (in any order):
- queue.eventA.send
- queue.eventB.send
- queue.*.send
- Stop the consumers on `queue.eventA.send` and `queue.eventB.send`.
- Wait until the queues are auto-removed as the queues now have 0 consumers (and 0 messages) (i.e. AMQ224112 logging appears)
- Start the consumers again
- The queues won't be auto-created now
- The consumers will start consuming from the `queue.*.send` queue -> its consumer count will raise from 1 to 3
If you were to do the same but the 'eventB' queue is not auto-deleted, that consumer will work just fine.
To me, it feels like some internal divert remains when the queue is auto-deleted, causing it to not be created again and therefore messing up how my messages are consumed. Is this expected behavior?
My (relevant) address settings are:
- Address full policy = Page
- Auto create addresses / queues = true
- Auto delete addresses / queus = true -> when I switch this to false I can prevent the issue from occuring
- Auto create dead letter & expiry resources = false
- Routing type: Anycast
- Address pattern: queue.#
I tested on the 2 artemis versions mentioned.
