Hi Kevin,
I installed the JBoss Messaging 1.3.0GA in Jboss AS 4.2.0.GA.
I ran the multithread test and I have not get "the connection pool was exausted" in jboss console, how before related in this topic.
Each thread have executed a loop with 40 iteration to force using all pool size (20).
Claudio, please move the discussion to the entry Kevin created and mentioned earlier. This topic has become too difficult for people to track now here. Thanks.
