I using JBM 1.4.0.SP3 to send messages to a remote MDB. The original messages are sent from clustered JBoss AS with a clustered queue. I'm sending multiple messages in a single session and reading the reply from the MDB using a temporary queue. I noticed that if I send many messages (over 200) to the MDB, I will very frequently not get 200 replies back. However if I send the messages in batches (of say 50) and then drain the reply queue each time, I get all the reply messages. What do you make of that ?????!!
