Example of incorrect setting 1
C : Paging file whose size is smaller than the installed memory size
D :
Paging file whose size is "installed memory size + 400 MB* " or more
→
The paging file in drive C is used for collecting memory dump, but
collection may fail because the size of the paging file is smaller than the
installed memory size.
Example of incorrect setting 2
C :
Paging file whose size is "installed memory size x 0.5"
D :
Paging file whose size is "installed memory size x 0.5
E :
Paging file whose size is 400 MB*
→
The total paging file size in all drives is "installed memory size + 400 MB*
", but collection may fail because only the paging file in drive C is used for
collecting memory dump.
Example of incorrect setting 3
C :
No paging file exists
D :
Paging file whose size is "installed memory size + 400 MB* " or more
(in dynamic volume)
→
Paging files in a dynamic volume cannot be used for collecting memory
dump. Thus, collecting memory dump fails.
*
This value is installed memory size +1,100 MB when the installed memory size is 4 TB or more
Specify a drive other than the system drive for "Dedicated Dump File".
Create the registry shown below by using the Registry Editor and specify the name of
Dedicated Dump File.
<For example: "dedicateddumpfile.sys" in drive D>
Note the following when specifying Dedicated Dump File:
The setting is applied after restarting the system.
Specify a drive that has free space of “installed memory size + 400MB (installed
memory size + 1,100 MB when the installed memory size is 4 TB or more)” or
more.
Dedicated Dump File cannot be placed in dynamic volumes.
Dedicated Dump File is only used for collecting memory dump, and is not used
as memory. Specify the paging file size so that sufficient virtual memory can be
allocated in the entire system.
Key : HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\Control\CrashControl
