SNAPMP Memory Leak After Host-Initiated Password Change

ID: Q193829

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.

RESOLUTION
