SYMPTOMS

When an application uses some Server Message Block (SMB) functions, such as accessing shared files or folders, on a Windows 2003-based computer that has multiple processors installed, the SMB functions time out earlier than expected.

CAUSE

This problem occurs because of a race condition in the SMB redirector.

RESOLUTION

Windows Server 2003

MORE INFORMATION

For example, this problem occurs in the following scenario:
  • The client uses an application that connects to a remote computer that is running Windows Server 2003 and SQL Server 2008.
  • The application obtains a handle to a FILESTREAM file. The application may do this by using the OpenSqlFilestream API or the .NET SqlFilestream class.
  • The application writes to the handle. Then, the application closes the handle.
  • The FILESTREAM file belongs to a table that has a potentially long-running update trigger installed. The application postpones the close handle operation until the trigger finishes its execution. However, because of a problem in the SMB protocol, the close handle operation times out earlier.
  • The close handle operation times out. Therefore, the associated SQL Server transaction is invalid. Therefore, the attempt to commit the transaction fails.
For more information about the FILESTREAM feature, visit the following Microsoft Developer Network (MSDN) Web site:
