The information in this article applies to:
- Microsoft Windows NT Server 4.0 Terminal Server Edition
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q179827 SYMPTOMS
After a fairly long period of continuously using Attachmate Extra V6.3, the
computer displays blue screen errors randomly.
CAUSE
These blue screen errors are caused by an application containing a registry
handle leak. This leak occurs because an application continuously reopens a
registry key but never closes it. After this has happened 65,535 times, the
open instance count for this key wraps round to zero making the kernel
think that there is no longer any open handles to this key. The next time
an instance of the key is closed, the storage used by the kernel to
reference the key is deleted.
However, any time subsequent to this that the key is opened or closed, the
freed storage is written to again. This causes free pool corruption and
eventually the system will crash when this freed storage is referenced in
any way.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the
