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(@org.jboss.ejb3.annotation.Pool)">
  |          @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/reference/1.0.7/html/SessionBean_and_MDB_configuration.html
