You can configure Windows NT to dump system memory to a file called
Memory.dmp when a severe error (called a STOP error or fatal system error)
occurs. This log file can be valuable for debugging the cause of the STOP
error.
NOTE: Before troubleshooting the problem, ensure that the computer is
properly configured to save a crash dump file. For more information, see
Chapter 5 of your Windows NT Workstation or Windows NT Server "System
Guide."
The following are several reasons why the Memory.dmp file is not being
created when your computer encounters a STOP message:
- The Memory.dmp file already exists and the option Overwrite Any
Existing File (found in Control Panel System) is not selected. It
is a good idea to leave this box checked and to move or copy the
current Memory.dmp file.
- The paging file on the %systemroot% drive is not large enough. The %systemroot% drive is the drive that contains the Winnt\System32 folder. To use the Write Debugging Information To feature, the paging file on the %systemroot% drive must be large enough to hold all of the physical RAM plus 12 megabytes (MB).
- The paging file is not on the %systemroot% partition. When the STOP error occurs, the system crash dump is written out to the pagefile on the root of the %systemroot% drive.
- There is not room for the Memory.dmp file in the path specified in
Control Panel for writing the memory dump.
- It is possible that the SCSI controller is bad or the system crash is
caused by a bad SCSI controller board.
- Certain computers and SCSI controllers do not permit the crash dump
information to be created. To determine if more information is
available, query on the following words in the Microsoft Knowledge
Base:
<your computer model> and Memory.dmp
NOTE: The administrator can configure the computer to generate system
event log and to send alerts to specific computers or users upon a system
crash. This is a very useful feature of Windows NT for monitoring systems
for system crashes when away from computers and when system configured for
automatic reboot.
