A dedicated complete memory dump file may not be successfully generated if the volume that stores the dedicated dump file has insufficient free space
Consider the following scenario on a Windows Vista-based or Windows Server 2008-based computer:
- You configure the computer to generate a complete memory dump file when the system crashes.
- You use the DedicatedDumpFile registry entry to specify the location for the dump file.
In this scenario, after the system crashes, the memory dump file may not be successfully generated. Instead, you find a file that is named dump
This problem occurs if both following conditions are true:
- The dedicated dump file and the system memory dump file are in the same volume.
- The free space on the volume that you specified for the dedicated dump file is less than two times the physical memory size of the computer.
