Searching is a wonderful thing.
While you are basicly correct, I would like to take the liberty to add a few side notes:
the netradiant windows build is 32 bit. While he might have plenty of RAM, the maximal user-mode virtual address space for each 32-bit process is 2G (as per
MSDN). If you need more than two gigabytes to compile the map, you might be out of luck. On the other hand, you should not be needing that much memory to compile it in the first place.
This is most likely a case of
broken map.
