The most probable reason for this is that your DOS box is not
configured correctly. Did you type the value 65535K in the DPMI
memory setting of the DOS box property sheet, as the FAQ tells
(section 15.6)?

AFAIK, on Windows the swap space comes from the Windows swap file, not
from DJGPP-specific swap file. DJGPP programs don't have anything
linked into them that creates/opens a swap file; they expect the DPMI
host to handle that.

How do you know how much DPMI memory is there available? Run go32-v2
with no arguments, and whatever it reports is the amount of memory
available to DJGPP programs. If that amount seems too low, you should
debug your configuration.

Not necessarily; DJGPP generally leaves it to the DPMI host to page
out the parent as needed. Please read the DJGPP FAQ list, section
15.8 for more details on this.
