[GRASS-user] Virtual memory available to cygwin GRASS

[Jonathan Greenberg]

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!
