durable subscription problems

t; attributes for on Remote (vaguely recommended in the docs) doesn't seem to have any effect. This seems very similar to this issue from February 2009: http://old.nabble.com/Confusion-about-dynamicOnly-NetworkConnector-property-td22211600.html, which didn't seem to get resolved.

Re: producer flow control and message cursors

One additional question: When using the default store-based message cursor, what happens when the store is full? Does ActiveMQ throw an exception to the producer, or does it block until messages are consumed? Joe Niski IS Development | NWEA PHONE 503.212.3382 | FAX 503.639.7873 NWEA.ORG
