 Replying to [comment:6 mehmeto]:
 > 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.
