Applications with large number of repetitive file operations slow, and eventually crash

Environment

Novell Client 2 SP4 for Windows
Client for Open Enterprise Server 2 SP4 (IR3)

Situation

Applications that repeatedly open, read/write and then close large numbers of files consume ever-increasing amounts of non-paged ncpl pool memory, as observed in poolmon.exe. 

The memory never gets released. Once it reaches a critical point, the computer slows to a crawl and will eventually BSOD.

Resolution

Fixed in Client for Open Enterprise Server 2 SP4 (IR4) or later.

Cause

A memory leak in ncpfsp.sys causes growing non-paged memory pool utilization during repetitive file operations.
