SYMPTOMS
In a Systems Management Server (SMS) 2.0 site, Discovery Data Manager (DDM) may stop processing Discovery Data Records (DDRs) in the Sms\Inboxes\Ddm.box folder. This behavior may occur after you establish a remote control session with an SMS client. In large SMS hierarchies, this may cause a backlog of DDRs.



CAUSE
This problem is caused by a blocking issue with the SMS database on the computer running Microsoft SQL Server.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
When DDRs are in process, DDM performs Select and Delete operations on the System_SMS_Instal_ARR table in the SMS database. Through this process, it locks portions of the table. The remote control process queries the SQL database to verify that the user who is trying to establish the remote control session has the necessary permissions. When a remote control session is executed, a Select statement is issued against the System_SMS_Instal_ARR table, and this creates the blocking condition. The computer running SQL Server recovers by ending the DDM process.
