> Tried to do the same analysis with Spearfish data that also is in the
installation package and it worked. It should be a memory problem indeed.
(although Spearfish map looks larger) Thanks for your replies.
You need to run r.watershed in disk swap mode with the -m flag. Also be
aware that even for smaller regions, the size of the temporary files can
be quite large, and LFS for Windows is only available in GRASS 7.
