Microsoft distributes Microsoft SQL Server 2008 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release.
Consider the following scenario:
File system error: While attempting to read information from disk, a read error occurred for physical file: <filename>, logical file: . Errors in the OLAP storage engine: An error occurred while the '<attribute>' attribute of the '<dimension>' dimension from the '<database>' database was being processed.
This problem occurs because a race condition exists where a thread reads a temporary file (.tmp file) that is being written by another thread of Lazy Writer.
The fix for this issue was first released in Cumulative Update 3 for SQL Server 2008 Service Pack 1. For more information about this cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:

To work around this problem, use one of the following methods.
In the affected dimension, remove referential integrity violations, such as duplicate keys and null keys.
Avoid multipass processing of the dimension.
Analysis Services engine uses multipass processing if it cannot fit all related attributes of a dimension in memory when it processes the dimension. Therefore, if you add more memory to the system, or you use large attributes that have less related attributes, multipass processing can be avoided.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
