Symptoms

Consider the following scenario:

  • You run Microsoft System Center Data Protection Manager (DPM), and you install the DPM agents on Microsoft SharePoint farm servers.

  • You create a DPM protection group to protect this SharePoint farm.

  • You run a backup job.


In this scenario, the backup fails intermittently, and SQL Writer experiences a deadlock condition that leaves sites in the server farm unavailable.

Note This deadlock condition may occur when other requestors outside DPM are used. Additional services outside SharePoint may also be affected.

Windows 7 and Windows Server 2008 R2 file information and notesImportant Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
