Memory dump file is not generated in Windows Vista or in Windows Server 2008 if the system drive is not larger than 4 times the amount of RAM
Consider the following scenario:
- You enable the Automatically manage paging file size for all drives option on a computer that is running Windows Vista or Windows Server 2008.
- The system drive size is not larger than 4 times the amount of installed random access memory (RAM).
- You configure the operating system to generate a complete memory dump file or a kernel memory dump file when a Stop error is encountered.
- A Stop error is encountered.
In this scenario, the memory dump file is not generated.
Note: If you add the IgnorePagefileSize registry entry in order to generate the memory dump file when a Stop error is encountered, the memory dump file is generated. However, the memory dump file might be truncated because of the paging file size.
