Bug number: 237 (SQL Hotfix)



''Microsoft distributes Microsoft SQL Server 2005 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 200 fix release.''



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by this hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart the computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
When you repeatedly run a Microsoft SQL Server 2005 Analysis Services Multidimensional Expressions (MDX) query, you experience the following symptoms:  Every time that you run the query, it takes longer to finish. For example, the first time that you run the query, it might take 15 seconds to finish. When you run the same query again, it might take 36 seconds or more to finish. If you monitor memory consumption on the server from which you run the query, you notice that private bytes usage and virtual bytes usage quickly increase. If you run the query a particular number of times, you receive the following error message:

Memory error: Allocation failure : Not enough storage is available to process this command.



Note This problem occurs when you use the MDX query together with the DrillDownMember function.



CAUSE
This problem occurs because of a memory leak in the DrillDownMember function.
