Spring amqp RPC request to rabbitmq getting timeouts

Question

I'm using the AmqpTemplate.sendAndReceive func from several servers, it works and the reconnection works after rabbitmq restarts or network problems.

It worked great for several weeks but suddenly one of my servers is getting timeout for every sendAndReceive call, the rabbitmq is getting the message and it being processed but sendAndReceive don't get the response (the reply-timeout is set to 60 sec and it takes only few sec to process the message). Other servers worked at the same time with the same code and using the same queue.

The server returned to work only after I restarted the service on it.

I think it's some reconnection problem (even though the messages sent to rabbitmq successfully), maybe the AmqpTemplate response listener didn't reconnect or something.

Anyone knows what might be the problem? and how I can prevent it to happen again?

my ConnectionFactory setting:

setConnectionTimeout(1000);
setRequestedHeartbeat(100);
setTopologyRecoveryEnabled(true);
setAutomaticRecoveryEnabled(true);

Edit:

Spring-AMQP version: 1.4.3

<bean id="myConnectionFactory" class="path.to.myConnectionFactoryClass"></bean>

<rabbit:connection-factory id="myRabbitConnectionFactory" connection-factory="myConnectionFactory" channel-cache-size="25" />

<rabbit:template id="myTemplate" connection-factory="myRabbitConnectionFactory" reply-timeout="65000" />

Edit:

It happened again, I see that it stop working after I get the error:

Not sure why the connection closed and why it didn't reconnect.

Answer 1

I think it being solved. I didn't catch an exception in OnMesaage, and I believe it killed my listeners.

Answer 2

at org.springframework.amqp.rabbit.core.RabbitTemplate.sendAndReceive(RabbitTemplate.java:820)

at MyClass.onMessage(MyClass.java:1234) ...

So this is not recovery of the server-side; your MyClass is invoking another rabbit template send and receive operation after receiving the message. So it is acting as a client in this situation.

However, normally, this exception would be thrown to the container, and rabbitmq will resubmit the message (unless you have acknowledge mode NONE), as long as your listener throws the exception to the container. If your listener catches the exception and does nothing with it except logging, you will see this result.

If you don't want rabbit to resubmit the failed message, or the inbound container does not acknowledge messages, you can configure a RetryTemplate into the outbound rabbit template to recover the connection; see the documentation.

If this doesn't explain your situation, you need to show the complete configuration, the code in MyClass.onMessage() and a complete log.
