Bug #: 353 (SQL Hotfix)

Bug #: 426313 (SQLBUDT)



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 2005 fix release.



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by the 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 run several concurrent queries against a Microsoft SQL Server 2005 Analysis Services database, the Analysis Services service may stop unexpectedly.



CAUSE
This problem occurs when the data cache mechanism lets multiple threads access the data cache registry and alter the data cache registry at the same time. When multiple threads access the data cache registry and alter the data cache registry at the same time, memory corruption may occur. When memory corruption occurs, the Analysis Services service may stop unexpectedly.
