Symptoms

Assume that you have Windows Server 2008 R2 Service Pack 1 (SP1)-based servers that use the Distributed File System Replication (DFSR) service. You have a DFSR replication topology in your environment. In this situation, you experience a spike of backlogs on a daily or weekly basis. Additionally, in the DFSR debug log, you notice that the "GcTask::refreshrecord" entry refreshes lots of records regularly.

Cause

This issue occurs when the garbage collection task (GCTask) of DFSR refreshes the stale records. When a garbage collection task processes the version vector tombstone of a content set before the non-version vector tombstone, the task considers all the records that belong to the content set to be stale. Therefore, the records are refreshed, and the issue that is described in the "Symptoms" section occurs.

Windows Server 2008 R2 file information notes
Important 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:

    VersionProductMilestoneService branch
    6.1.760 1.17xxxWindows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component.
