Bug #: 0002460 (SQL Hotfix)

SYMPTOMS

When you perform a processing operation or a query operation in Microsoft SQL Server 2005 Analysis Services, the operation fails. Additionally, you receive the following error message:
Error 0xC1020034. The following file is corrupted: FileDescription
Note The placeholder FileDescription represents information about the corrupted file.

This problem occurs after you install Cumulative Update 5 for SQL Server 2005 Service Pack 2.

CAUSE

This problem occurs because of a race condition that was introduced in Cumulative Update 5 for SQL Server 2005 Service Pack 2.

Note The build of Cumulative Update 5 for SQL Server 2005 Service Pack 2 is 09.00.3215.

When the race condition occurs, SQL Server 2005 Analysis Services marks a data page in memory. In doing this, SQL Server 2005 Analysis Services indicates that the data page has been written to disk. However, the marked data page in memory is not actually written to disk. The race condition prevents SQL Server 2005 Analysis Services from writing the marked data page in memory to disk. This situation may result in file corruption when the Windows operating system later discards the changed memory.

RESOLUTION

The fix for this issue was first released in Cumulative Update 6. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:
946608 Cumulative update package 6 for SQL Server 2005 Service Pack 2
Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

937137 The SQL Server 2005 builds that were released after SQL Server 2005 Service Pack 2 was released
Microsoft SQL Server 2005 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2005 Service Pack 2 hotfix to an installation of SQL Server 2005 Service Pack 2. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Microsoft discovered this race condition during ongoing internal testing. The race condition may occur while a background cleanup operation is executing if one of the following conditions is true:
  • The operation is executing on a server that has fewer than eight processors, and memory usage exceeds the high memory limit.

    Note The high memory limit is specified in the TotalMemoryLimit memory property. The TotalMemoryLimit memory property defines the total amount of physical memory that is available to SQL Server 2005 Analysis Services under typical operating conditions. Values smaller than 100 represent a percentage of memory. Values larger than 100 represent an absolute value in bytes.

  • The operation is executing on a server that has at least eight processors, and memory usage exceeds the midpoint between the low memory limit and the high memory limit.

    Note The low memory limit is set in the LowMemoryLimit memory property. The LowMemoryLimit memory property defines the low threshold of physical memory that is available to SQL Server 2005 Analysis Services. Values smaller than 100 represent a percentage of memory. Values larger than 100 represent an absolute value in bytes.
We recommend that you install the latest cumulative update package if you are running one of the following builds of SQL Server 2005 Analysis Services:

We consider the possibility of encountering the race condition to be small. After you install the latest cumulative update package, we recommend that you reprocess all cubes that were processed by using the builds of SQL Server 2005 Analysis Services that are mentioned in the previous bulleted list. By taking this action, you can make sure that the data that you process contains no corruption that is caused by the race condition.
