This article describes a hotfix rollup for Microsoft Visual Studio Team Foundation Server (TFS) 2010. This hotfix rollup includes the previously released hotfix that is described in the following Microsoft Knowledge Base (KB) article:

2655761 FIX: Time out occurs when Team Foundation builds are waiting for build agent reservations in Visual Studio Team Foundation Server 2010 Additionally, this hotfix rollup resolves several issues that are described in the "More Information" section.

More Information

Issue 1

It takes longer than expected to check in lots of files to a TFS source control if the size of the TFS database is very big.


This issue occurs because of a performance problem in the prc_PendAdd Transact-SQL stored procedure in TFS 2010.

Issue 2

When a TFS server is processing a merge operation, there may be connectivity issues.


This issue occurs because of a performance problem in the prc_PendMerge Transact-SQL stored procedure. The stored procedure locks a table until a time-out occurs on the TFS server.

Issue 3

Consider the following scenario:

  • You map a source-controlled folder in TFS 2010 to a local folder.

    Note The local folder has the same folder name as the source-controlled folder. However, the two folders' names differ only by case.

  • The source-controlled folder contains shelveset files of a shelveset, and the folder is not mapped to a build agent folder in the build definition.

  • You queue a build that uses the shelveset.

In this scenario, the build operation fails, and you receive an error message that resembles the following:

TF10122: The path 'shelveset file path' contains a '$' at the beginning of a path component. Remove the '$' and try again.


To work around this issue, map the source-controlled folder to a build agent folder in the Workspace tab in the build definition.
