Memory Dump Function for Windows (OS Standard Function)
If a fatal system error occurs, data in the physical memory is output to a file.
Dump Types and Estimated Sizes
Mechanism for Acquiring Dump Information
1. If a system failure occurs, dump information is output to the paging file in the boot volume.
2. After the OS is restarted, a tentative paging file is created, and the acquired dump information is
moved to the specified save destination.

Description
Dump file size
Complete memory dump
Records all data that exists in the physical memory when the
system stops.
Physical memory size + 300MB
Kernel memory dump
Records the information only in the kernel memory space.
Depends on the memory space during system operation.
Minimum memory dump
Records the minimum information that is useful for
identifying the problem.
128KB or 256KB
Automatic memory dump
Records information that is equivalent to the conventional kernel memory dump.
The following points are different from the kernel memory dump.
The initial value of the paging file size is smaller than the kernel memory dump size.
If part of the information in the kernel memory space cannot be recorded, the page file size is automatically extended after
the next startup. (If part of the information in the kernel memory space cannot be recorded, acquisition of memory dump
information may fail.)
For details, refer to "13.4.3 Setting up the dump environment (Windows)" in "Administration Manual".
