Thanks for the reply, but this is the behaviour of broker, what will this affect the producer? Will the producer simply gets notified that its message has been accepted/rejected and close the session or maybe it'll hang on there for a moment in certain cases.
Producer has set the delivery property to PERSISTENT, I used --store-dir to start the broker but I'm not sure if that means the queue is persistent. Also the producer and broker are using direct exchange. -----Original Message----- From: Gordon Sim [mailto:[email protected]] Sent: 04 June 2009 13:23 To: [email protected] Subject: Re: what does the producer client do if the queue in a qpid cluster is full?

It will depend on the policy set. The default policy for a temporary queue (for all queues if no store plugin is loaded) is to simply reject new messages (which will end the producers session). The default for durable queues is to write new messages to disk (whether or not the message itself is marked persistent) and then release the contents from memory to be loaded again for delivery to a subscriber. > Is > the behaviour going to be the same as the queue is shutdown?
