NEC Express5800 User Manual page 195

NOTES:
To specify "Complete Memory Dump" to write the debug
information is recommended. If the mounted memory size is larger
than 2GB, "Complete Memory Dump" cannot be specified so that
specify "Kernel Memory Dump" instead.
Specify the drive where there is a free area more than the size of
"the memory capacity mounted on Express workstation +
300MB".
In case the mounted memory size exceeds 2GB due to the added
memory, change the write debugging information to [Kernel
Memory Dump] before adding memory.
The size of debugging information (memory dump) to be taken
also changes due to adding memory. Verify the size of the empty
space in the debugging information (memory dump) write
destination drive.

On the [Paging file size for each drive] box, specify as follows:
– A value larger than the recommended size shown in [Total paging file size for all
drives] for [Initial size]
– A value larger than the [Initial size] for [Maximum size]
Then click [Set].
IMPORTANT:
The above-mentioned paging file size is recommended for
collecting debug information (memory dump).
The paging file with initial size large enough to store the dump file
in the boot drive is required.
Correct debug information might not be able to be collected due to
virtual memory shortage when the paging file is insufficient, so set
an enough size of the paging file with the entire system.
For more information on "Recommended" value, see "About the
System Partition Size" described earlier.
In case the memory is expanded, re-specify the paging file to suit
the new memory size.
