Sorry Chris but unless I've missed something then.....

mapid = 70020001
cache = ./
Checking for an existing cache and verifying contents...
No suitable cache was found. A new cache will be created to speed up the
splitting stage
Map is being split for resolution 13:
 - area boundaries are aligned to 0x800 map units
 - areas are multiples of 0x1000 map units wide and high

The input file is 3.9GB if that helps and r88 runs against the very
small test file I created when testing my script. If you need any other
info just ask.
