DOCUMENT:Q193829 20-MAY-2002 [sna] TITLE :SNAPMP Memory Leak After Host-Initiated Password Change PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:3.0,3.0 SP1,3.0 SP2,3.0 SP3,4.0,4.0 SP1 OPER/SYS: KEYWORDS:kbbuglist kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 3.0 SP3, 4.0, 4.0 SP1 ------------------------------------------------------------------------------- SYMPTOMS ======== After a password change is received and processed, a memory leak of 150 bytes per password change is observed. CAUSE ===== The Windows NT Account Synchronization service is responsible for synchronizing passwords between a host and a Windows NT domain. SNAHOSTPROCESS and SNAPMP work together to synchronize host-initiated password changes. SNAHOSTPROCESS is controlled by the Host Account Synchronization service. SNAHOSTPROCESS sends host-initiated password changes to SNAPMP via encrypted RPC. SNAPMP is not releasing the memory allocated for RPC responses during this process.
