Queues hang when there is no permission to publish

[dbampalikis]

If the configuration of the RabbitMQ doesn't give access to a user to publish to a specific exchange, the service hangs and requires restart.

For example here if the user doesn't have access to publish to the exchange, the message is not unacked and the next messages are not taken care of

i think we might be reaching a deadlock here, which i noticed also in other use case e.g. a ack is not sent by the service and the MQ timesout, causing a service to reach a deadlock. Not sure if the solution here rabbitmq/amqp091-go#123 would solve it 🤔
