another queue, you can encounter `AMQPConnectionException` with the message "Library error: a SSL error occurred" or "a socket error occurred"  depending on if you are using tls or not or if you are running behind a load balancer or not.You can manually reproduce this issue by dispatching a message where the handler then dispatches another message to a different queue, then go to rabbitmq admin and close the connection manually, then dispatch another message and when the message handler goes to dispatch the other message, you will get this exception:```a socket error occurred#0
