Consider the following scenario:
- You configure the system to generate a full memory dump file when fatal system errors occur on a computer that is running Windows Server 2008 or Windows Vista.
- The dump file and the paging file are configured to reside on the same volume.
- Sufficient free disk space is available on the volume for the dump file. For example, 10 gigabytes (GB) of free disk space is sufficient to save a full memory dump file on a computer that has 8 GB of physical memory.
In this scenario, a memory dump file may not be generated when a fatal system error occurs. However, you find a DumpXXX.tmp file in the location that you specified to save the dump file.
This problem does not occur if the free disk space is larger than two times the size of the physical memory. Additionally, this problem does not occur if the Memory.dmp file already exists.
