If you don' t use any persistent store, messages must be kept in memory, so you are obvisouly limited by the available mem. If you use a jdbc store, messages can be removed from memory and store for later consumption.

Would topics behave differently? I'm trying to put lots of messages on a topic with a disconnected durable subscriber. With ActiveMQ 4.0.1 in the default configuration the producer blocks after a few thousand messages. Giving it lots and lots of memory lets it receive some more messages, but at a few tens of thousands of messages it will block again. Do you have to configure the journal or JDBC persistance somehow to avoid this limitation? -- View this message in context: http://www.nabble.com/Paging-support-tf2163517.html#a6022232 Sent from the ActiveMQ - User forum at Nabble.com.
