DOCUMENT:Q280804 08-MAY-2002 [winnt] TITLE :Memory Leak in Mapsvc.exe When Synchronizing Many Users PRODUCT :Microsoft Windows NT PROD/VER::2.0 OPER/SYS: KEYWORDS:kbenv kbtool ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows Services for UNIX, version 2.0 ------------------------------------------------------------------------------- SYMPTOMS ======== The Mapping service in Services for UNIX may experience a memory leak when you are synchronizing many UNIX users that do not exist in the Microsoft Windows NT-based domain. CAUSE ===== For every UNIX user, the Mapping service performs a corresponding lookup for the Windows NT user. The Mapping service uses the LSALookUpNames function for this lookup, which allocates memory even if the function does not work. If a UNIX user does not exist in the Windows NT-based domain, the function does not succeed and no attempt is made to free the memory.
