Channel closing when application is restarting

[IkarVs]

Hello everyone,
I have a problem with an app i'm working on.
When my application gets an unexpected type of exception, i use
channel.basicNack(tag, false, true); SpringApplication.exit(context);
to stop the app and put the message in its original queue.
After that the application restarts and sometimes the application dies while starting with these kinds of logs :

 :: Spring Boot ::                (v3.1.0)

2025-04-28T07:53:38.315Z  INFO 1 --- [ionShutdownHook] o.s.a.r.l.SimpleMessageListenerContainer : Shutdown ignored - container is already stopped

I can see that the reason for it is an unresponsive consumer but i don't know how to fix it.
I've already tried to abort the channel, disable the restart main from spring devtools or disable the durable option of the Queue object that i'm using. I guess the problem comes from the way i'm stopping the channel but i can't manage to find the right way to do it.

I should mention that when the exception first arrives, i also get the logs of Waiting for workers to finish. and Workers not finished. except when i use channel.abort() but even with this i still get these at the restart.
I should also mention that i use the AcknowledgeMode : MANUAL

I'd love to get some help.
Thanks for your time
Have a great day !

You should not use channel.basicNack manually. Stopping an application normally should be enough to clean up all the resources.

You also should consider to upgrade to the latest Spring AMQP. We had some fix recently for stopping containers.

If that still doesn't work for you, please, share some simple project we can reproduce on our side.

Side note: GH comments allow us to post multi-line code snippet using triple back-ticks.
Otherwise that log is just not readable well for me right now.

Thanks for your answer.
I've tried to upgrade my spring version to the latest and getting rid of the basicNack but it didn't solve the problem, I will make a little project based on mine so you can reproduce this.
