title: Configure Geronimos MDB InstanceLimit
body: <p>I'm not able to configure Geronimo/ActiveMQ so that more then 10 Messages get processed at once. </p>
  
  <p>I tried the suggestions from this <a href="https://mail-archives.apache.org/mod_mbox/geronimo-user/200807.mbox/%3Cadd18bc80807171044u57cf26cfq467cf3eb29e7084b@mail.gmail.com%3E" rel="nofollow">mailing list</a>,
  but setting the <code>maxSessions</code> to something higher than 10 doesn't have any effect. Setting it to something lower than that has an effect though...</p>
  
  <p>Also I'tried to set the <code>InstanceLimit</code> by setting: </p>
  
  <pre><code>&lt;module name="org.apache.geronimo.configs/j2ee-server/2.1.4/car"&gt;
      &lt;gbean name="org.apache.geronimo.configs/j2ee-server/2.1.4/car?ServiceModule=org.apache.geronimo.configs/j2ee-server/2.1.4/car,j2eeType=GBean,name=CustomPropertiesGBean" 
             gbeanInfo="org.apache.geronimo.system.properties.SystemProperties"&gt;
          &lt;attribute name="systemProperties"&gt;Default\ MDB\ Container.InstanceLimit=50&lt;/attribute&gt;
      &lt;/gbean&gt;
  &lt;/module&gt;
  </code></pre>
