Bug #: 50000551 (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 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
Consider the following scenario. You create a merge publication in Microsoft SQL Server 2005. You configure Web synchronization for the merge publication. In this scenario, a memory leak may occur every time that you synchronize a Microsoft SQL Server 2005 Mobile Edition (SQL Server Mobile) subscriber. In the W3wp.exe process, the memory usage increases, and the number of handles increases.



CAUSE
This problem occurs because the Replrec.dll file leaks memory and leaks handles.
