TITLE   :Print Server Slow Down and GP Fault in LMSVCS.EXE
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:BUGLIST3.10 FIXLIST3.10.004

--------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT operating system version 3.1
 - Microsoft Windows NT Advanced Server version 3.1
--------------------------------------------------------------------------

SYMPTOMS
========

Your computer slows down and a User Mode general protection (GP) fault in
LMSVCS.EXE message appears. This problem is most apparent on Print Servers
because it is triggered by the XsNetPrintJobEnum() application programming
interface (API). Stack trace information may vary depending on current
machine activity.

CAUSE
=====

There are two causes for this problem. First, the XsNetPrintJobEnum() API
does not free allocated memory upon completion. Repeated calls to this API
cause the heap to fill with allocated memory blocks and interleaved 96K
sections of uncommitted memory. Second, when the heap is completely filled
(64 MB), the heap manager does not handle the situation and causes a GP
fault or disappears from memory.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Windows NT and
Windows NT Advanced Server version 3.1. A fix to this problem is in
development, but has not been regression-tested and may be destabilizing in
production environments. Microsoft does not recommend implementing this fix
at this time. Contact Microsoft Product Support Services for more
information on the availability of this fix.
