- 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.
