rabbitmq channel shutdown with PRECONDITION_FAILED - fast reply consumer does not exist

问题

We are getting the below error when we are posting a message to rabbitmq from a spring boot service. Also this is intermittent and we are not able to reproduce this.

[AMQP Connection 123.11.xxx.xx:5672] ERROR [] org.springframework.amqp.rabbit.connection.CachingConnectionFactory - Channel shutdown: channel error; protocol method: #method(reply-code=406, reply-text=PRECONDITION_FAILED - fast reply consumer does not exist, class-id=60, method-id=40)

Does anyone faced similar issue with rabbitmq . Please help us with your inputs.

回答1:

It most likely means the requestor has timed out and canceled the consumer on the direct replyTo queue. Or, the requesting application has been stopped.

If the requestor is also a Spring AMQP application, the default replyTimeout is 5000ms (5 seconds). If the server side takes longer than that, the requestor will timeout and you'll get this error on the server.

You can increase the replyTimeout property on the requesting RabbitTemplate.

EDIT

Spring AMQP 2.0.x (requires Spring Framework 5.x) uses longer-lived direct replyTo consumers so you shouldn't get these messages (but the client will still time out and you'll get a warning log on the client side and a log when the late delivery arrives).
