title: SqlDependency / Broker : Broken Notifications
body: <p><br/>I begin with the broker notification system.<br/>
  I use SqlDependency to notify data updates beetween application instances.<br/>
  Overall, it works well. But sometimes, after a while, I don't receive no more notifications.<br/>In SQL management activity monitor, processes keep <em>"BROKER_RECEIVE_WAITFOR"</em> wait type.<br/>Also, I notice this error in SQL Server 2008 R2 log : <em>"The query notification dialog on conversation handle closed due to the following error ... (-8470) Remote service has been dropped"</em>.<br/>Is there a particular setting to avoid shutdown dialog notifications ?<br/>Thanks in advance for your help.</p>
