There are ongoing issues with various windows incarnations of GRASS.
Cygwin has had some issues with large files and higher memory addressing
pretty much since its incarnation (I wrestled with this quite a bit a
few years back). You might want to try the new grass binary that relies
on mingw, I've seen my memory spike higher than 1gb during some
analyses... or, install unix someplace!

Hello,
As a less-than-two-year old cygwin/GRASS user, I have never seen
virtual memory going over 1 GB while doing intensive computations with
GRASS (e.g., v.surf.idw interpolation). I haven't found much on the
topic in the web so I tried the following to increase virtual memory
available to cygwin:

but noticed no difference and so I am wondering whether cygwin/GRASS
gets compiled with the -mno-cygwin flag that apparently allows
programs to allocate up to 1920 MBytes:
http://sourceware.org/ml/cygwin/2005-04/msg01309.html
Does anybody has experience with this?
Thanks and regards,
Luigi
