The client must be configured to request heartbeats. RabbitMQ will route the message from the OrderSystem.Events:OrderSubmitted exchange to the order-events-listener exchange, and subsequently to the order-events-listener queue. A typical mistake is to have an unlimited prefetch, where one client receives all messages. The heartbeat timeout value defines after what period of time the peer TCP connection should be considered unreachable (down) by RabbitMQ and client libraries. On the server side, the limit is controlled using the channel_max: # no more 100 channels can be opened on a connection at the same time channel_max = 100. You can expand it, but the root problem is usually that you are now and then sending unreasonably large messages that needs to travel over link between the nodes (and the encoding for . The client must be configured to request heartbeats.

The heartbeat timeout value defines after what period of time the peer TCP connection should be considered unreachable (down) by RabbitMQ and client libraries.

The value is configurable for both RabbitMQ and client libraries.

This can lead to the client running out of memory and crashing, and then all messages are re-delivered. > > Hi Adam, > > I have seen similar messages in the past, but haven't really looked > into it. conf{heartbeat,Timeout}Timeout .
