MessageRejectedWhileStoppingException while stopping

[nima]

Hi,
I'm using spring-amqp along with RabbitMQ message broker which receives the messages from the queue and process them. also, I need to manage the incoming traffic from the MessageConsumer which reads from the queue and pass it to the core of application, so I created a InputTrafficMonitor bean which decides whether to stop/start the incoming traffic (from the message consumers) with stop/starting the injected SimpleMessageListenerContainer bean ( with calling the corresponding stop/start methods - I don't know if it's the right way to do that or not);
so I started a stress-test and found that some messages is being lost in the case of stopping the messageListenerContainer ! I checked the logs and found bunch of MessageRejectedWhileStoppingException s as follows :

2012-10-29 14:55:19,004 WARN  [amqp.rabbit.listener.SimpleMessageListenerContainer:557] - Consumer raised exception, processing can restart if the connection factory supports it. Exception summary: org.springframework.amqp.rabbit.listener.MessageRejectedWhileStoppingException: Message listener container was stopping when a message was received

I. any clue how to handle/solve this problem ?
II. is there any better way to pause the incoming traffic from the consumers rather than stop/starting the MessageListenerContainer ?

thanks in advance
