[GRASSLIST:8370] Re: r.terraflow, or system, out of memory

[Cannata, Massimiliano]

Do you have enough space on your tmp file?
terraflow use temp file that can result quite big...
it happened to me that was the cause of crashing the 
command and leaving trash on the tmp dir (i can't remember 
now but there's a way to define which dir use as temp)....
Don't know if it is related...
Hope can helps.
