SYMPTOMS

In Microsoft SQL Server 2005 or in Microsoft SQL Server 2008, you enable query notification for a database, and you back up the database. However, when you try to restore the database from the backup file the regular startup process, and the startup process in the recovery phase take a long time to finish. Additionally, the following error messages are logged in the SQL Server 2005 Errorlog file:

Date Time SPID Query notification delivery could not send message on dialog '{Dialog ID}.'. Delivery failed for notification '?<qn:QueryNotification xmlns:qn="http://schemas.microsoft.com/SQL/Notifications/QueryNotification" id="2881" type="change" source="database" info="restart" database_id="7" sid="0x010500000000000515000000FA48F22A6990BA52422C73DFF9030000"><qn:Message>4a4c696b-645c-40fd-bfef-4f2bc7c599b4;eb99973e-3cc9-4c7e-b4b9-47d8cf590c43</qn:Message></qn:QueryNotification>' because of the following error in service broker: 'The conversation handle "<Conversation Handler>" is not found.'.

CAUSE

When you restore a database, SQL Server tries to redo all the query notification transactions as part of the database startup. However, the processing of query notifications may fail if there is no application listening for them any longer. This causes SQL server to log error messages to the Errorlog file for each query notification message delivery failure. If there are many query notification message delivery failures, SQL Server takes a long time to log all the error messages in the Errorlog file. This results in a bottleneck, and causes the recovery of the database to take a long time.
