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.
