[rabbitmq-discuss] Trying to handle ConnectionShutdown event

Wed Nov 28 13:40:38 GMT 2012

Yeah, that is the problem. My code does uses the original name as a handle (was assuming when I started that the queueName was static). Fortunately I have encapsulated all RabbitMQ calls in its own class so I can work around this problem. I just hoped I didn't have to.

Thanks,
Bernhard

Auto-deletion is only useful when there can be multiple consumers. Those multiple consumers would all need to know the queue name. Which usually implies it is known in advance, rather than server-generated and then shared.

By contrast, if the queue is exclusive then it will get deleted when the connection closes. Server-named queues work well here. When reconnecting, simply declare a queue the same way as you did initially, i.e.let the server pick a (new) name. For that to work, obviously none of your code must hold on to the original name.

Matthias.
