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
Please, see below (2 warnings before crash).
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,
