[GRASS-user] r.watershed G_malloc error

[Michael Spencer]

Hi All,

I'm on windows xp using GRASS 6.4 and 7 and I'm getting the following error running r.watershed:

ERROR: G_malloc: unable to allocate 2521456396 bytes of memory at init_vars.c:137

I've 2Gb of ram and the dtm I'm using is 185Mb in (pre import) ascii grid format, so not massive. Is the above error because I'm short on ram for the above process, or is it something else?

Cheers,
Michael
