Monitoring service plugin response not complete

Hi,

OS is Windows 2003 Server, DB is MS SQL 2005.

my problem is: i dont get a complete response for my request to get archived messages.

Request stanza:

<iq type='set' id='GetArchivedMessages'>

  <query xmlns='urn:xmpp:mam:0'>

    </x>

    <set xmlns='http://jabber.org/protocol/rsm'>

      <max>100</max>

    </set>

  </query>

</iq>

Response from openfire server:
