Dedicated dump files are unexpectedly truncated to 4 GB on a computer that is running Windows Server 2008 or Windows Vista and that has more than 4 GB of physical memory
Consider the following scenario:
- On a computer that is running Windows Server 2008 or Windows Vista, you have more than 4 gigabytes (GB) of physical memory installed.
- The system is configured to generate a full memory dump file.
- The DedicatedDumpFile and DumpFileSize registry values are created. The value of the DumpFileSize parameter is larger than 4096.
In this scenario, the generated dump file is unexpectedly truncated to 4 GB.
Note: To deploy, troubleshoot, and service large memory platforms, OEM partners and customers may have to create large dump files.
