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.
This article describes the following about this hotfix release:
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.
This problem occurs because the Replrec.dll file leaks memory and leaks handles.
