Yes, for some time that "ghost" connection may be present until server realises the client has gone but I do not see how it prevents your service from successfully restarting.</div><div>If you declare queue as auto-delete, non-durable, non-exclusive and your user is permitted to do it the first time, then later when your service restarts and the queue already exists, you will still be able to declare it again with the same parameters. It won't cause error. So your second service will be able to start consuming from the same queue.</div><div><br></div><div>However, I have a strong feeling that what you really need instead is exclusive queue which you declare without providing a name so the server chooses a random name for you. So each time your service starts - a new queue is created and it ceases to exist when connection disappears.

After reboot, the service starts and when trying to create the queue, it conflicts with the former queue. We tried to create the queue as exclusive, but it doesn't allow us to connect because we haven't permission.</blockquote>
</div><br></div>Is it because you have multiple connections using the queue?</div><div class="gmail_extra"><br clear="all"><div>If you consumer from the queue, you can declare it as auto-delete and non-durable instead of exclusive. Then as soon as the last consumer (registered with basic.consume, not using basic.get) is gone, it will be deleted.</div>
