Hello, I hope I have chosen the right forum ... I have a MDB that receives data to process from an external application. Currently this works very well. In rare conditions there can be really a flood of messages, so there may be thousands of messages, waiting to be processed by the MDB. My question now is: Is there a max size of the message queue? Is there a risk that messages might get lost, if there are much more messages than can be processed at the moment? By the way: I am using JBoss 4.2 Thanks in advance for every answer Andreas View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4264273#...
