Microsoft distributes Microsoft SQL Server 2008 R2 Service Pack 2 (SP2) 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 R2 Service Pack 2 fix release.
Symptoms
Assume that you run multiple Multidimensional Expressions (MDX) queries in parallel in Microsoft SQL Server 2008 Analysis Services (SSAS 2008), Microsoft SQL Server 2008 R2 Analysis Services (SSAS 2008 R2) or Microsoft SQL Server 2012 Analysis Services (SSAS 2012). The queries cause an MDX error. However, while the different query threads generate the MDX error strings, a heap corruption occurs. Therefore, SSAS may crash.
