Dear all,
I am trying run a r.watershed command with one 7200x7200 DEM map.
But after one day running, the system crash without finish the output
generation.
Please, see below (2 warnings before crash).
little strange, I run r.watershed (but on ubuntu not windows) with
raster file 4500 x5000 and it takes no more than 2 minutes.
Tell us more about grass version you use (probably you use old version
of r.watershed)

By the way I am running grass 6.4.0 SVN (rc4?) under Msys/Vista
on a 6Gb/64 bits machine.
Thanks for the help,
milton
