In Microsoft SQL Server 2005 Analysis Services, when the workload demand on the server is high, the server stops responding. Additionally, you receive the following error message:
Internal error: An unexpected exception occured.
When this issue occurs, a minidump file is generated in the SQL Server 2005 Analysis Services log folder.
This issue occurs because an error is generated when SQL Server 2005 Analysis Services processes data in a multithreaded manner. This results in a shared data structure that is incorrectly manipulated by multiple threads at the same time. Therefore, the shared data structure is corrupted, and an exception is generated.
Note The error message may be caused by other issues. We recommend that you contact Microsoft Customer Support Services to determine whether you are experiencing the problem that is described in this article.
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:

Restart information
You do not have to restart the computer after you apply this hotfix. However, this hotfix stops and then restarts the Analysis Services service. If you configured the server for HTTP access, you must stop and then restart Internet Information Services (IIS) after the installation is complete. If you installed Analysis Services as a named instance, you must stop the SQL Server Browser service. You must do this because the Msmdredir.dll component of the SQL Server Browser service is updated during the installation of this hotfix.
Registry information
You do not have to change the registry.
