Symptoms

You have Microsoft Office SharePoint Workspace 2010 clients or Microsoft Office Groove 2007 clients. These clients are provisioned to Microsoft Office Groove Server 2007 Relay or Microsoft Office Groove Server 2010 Relay on a computer that is running Windows Server 2008 R2. These clients may occasionally experience the following problems:

  • A Groove Workspace synchronization error.

  • Groove instant messages that are transmitted through the relay server are missing.

The affected SharePoint Workspace client will recover from the data loss by resending the workspace data automatically. However, the affected workspace may be unrecoverable in some instances. When this problem occurs, the relay server administrative trace log contains one of the following error messages:

  • GCFFQOpGetNext::CompleteMessageAvailable: From canonical failed

  • GCFFQOpAdvance::AdvanceMessage: Advancing already deleted message

  • GCFFQOpGetNext::SendCachedMessage: Can't send

Cause

This problem occurs because of a race condition in the NTFS file system. This behavior may cause write failures.Groove Server 2007 Relay or Groove Server 2010 Relay that is running on Windows Server 2008 R2 may occasionally not persist end user data to disk. This behavior may occur under heavy server load conditions. This behavior may also occur when a client is updating the content of a workspace that has a large number of participants.
