If the header is present rabbitmq.MANDATORY it will override this option. I turn rabbitmq off, wait then turn it back on.

If the connection goes down unexpectedly, a new one is automatically created by using Connection.NotifyClose listener (handled by RabbitMQ.reconnect() method) or RabbitMQ.Channel() method as soon as first publishing occurs. Connect method connects to the rabbitmq server and creates push/listen channels if they don't exist. We rely on the default exchange in the broker (since none is specified in the send), and the default binding of all queues to the default exchange by their name (thus, we can use the queue name as a routing . Connect and share knowledge within a single location that is structured and easy to search. I'd start by moving (not deleting!) channel channel.close () . application . to rabbitmq-users Nothing in those messages tells us that the node had to shut down. The following examples show how to use com.rabbitmq.client.ShutdownSignalException.These examples are extracted from open source projects.
