Hi Andrew, 1. I apologize for my bewildering request for a clarification of "each time it fires". I read too quickly and missed "a MDB" from the beginning of your question, and I thought "JBoss Messaging" was the antecedent of "it". 2. With your help I was able to reproduce the WARNING message, and I see why it's happening. I'll explain further in the related thread http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040864#... However, the cause is benign, and I'll make the message go away in the next release. Thanks for your help. -Ron View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4041276#...
