[GRASSLIST:8369] r.terraflow, or system, out of memory

[Michele]

Hi,

i'm running r.terraflow (grass6.0.1) on a large:

nsres:      2
ewres:      2
rows:       10050
cols:       7760

raster and the process seems to stop out of  the blue, i know that this module works on the same machine on an subset of the data i'm working on.
Anyway i don't understand if this is an r.terraflow problem (I've searched in the bug/whishlist and didn't find anything related) or a kernel problem, indeed i found in  /var/log/messages

 kernel: __alloc_pages: 0-order allocation failed (gfp=0xf0/0)

Do someone experienced somethig like that and knows how to fix?

Thanks, Michele.
