for the first time, I'm running into a deadlock on ...The deadlock graph doesn't help me much except the fact the query notification system seems to responsible.

  <resource-list>
   <keylock hobtid="72057654759522304" dbid="6" objectname="MyDB.sys.query_notification_814081939" indexname="cidx" id="lock15ab2aa80" mode="RangeX-X" associatedObjectId="72057654759522304">
    <owner-list>
     <owner id="process5c5708" mode="RangeX-X"/>
    </owner-list>
    <waiter-list>
     <waiter id="process4e9ae08" mode="RangeS-U" requestType="wait"/>
    </waiter-list>
   </keylock>
   <keylock hobtid="72057654759522304" dbid="6" objectname="MyDB.sys.query_notification_814081939" indexname="cidx" id="lock15e56a300" mode="RangeS-U" associatedObjectId="72057654759522304">

     <waiter id="process5c5708" mode="RangeS-U" requestType="wait"/>
    </waiter-list>
   </keylock>
  </resource-list>
