We have 2 jboss running clustered. We are publishing Messages of a Topic, the Topic is deployed in node_1. If our application is publishing the message, using beans on node_1 the message-driven beans (registered to the Topic) on both of the nodes are starting and work (as we wanted). Problem: If the application is publishing on node_2 (where the singleton Topic isn't deployed) the message is published, but no MDB is starting. Why can our Messages 'disappear' ?
