The Message Driven bean configurations in JBOSS_HOME/server/< serverName>/deploy/ejb3-interceptors-aop.xml is configured to use StrictMaxPool with max 15 instances: <domain name="Message Driven Bean" extends="Intercepted Bean" inheritBindings="true"> | ... | <annotation expr="class(*) AND !class((a)org.jboss.ejb3.annotation.Pool)&quot;&gt; | @org.jboss.ejb3.annotation.Pool (value="StrictMaxPool", maxSize=15, timeout=10000) | </annotation> | </domain> | In combination with the maxSession value, also configure your MDB to set the Pool size of your choice, as explained here http://www.jboss.org/file-access/default/members/jbossejb3/freezone/docs/...
