[GRASS-user] G_malloc: out of memory

[Kurt Springs]

I used g.region  to set the resolution from 10m to 100m, then to 1m.

on 100m I get

PNG: GRASS_TRUECOLOR status: TRUE

PNG: collecting to file: /Users/kurtsprings/grassdata/OSI0834/ 
PERMANENT/.tmp/Kurt-Springs-MacPro.local/5417.0.ppm,

      GRASS_WIDTH=309, GRASS_HEIGHT=482
d.rast(5512) malloc: *** mmap(size=1206358016) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

G_malloc: out of memory

on 1m I get



PNG: GRASS_TRUECOLOR status: TRUE

PNG: collecting to file: /Users/kurtsprings/grassdata/OSI0834/ 
PERMANENT/.tmp/Kurt-Springs-MacPro.local/5417.0.ppm,

      GRASS_WIDTH=309, GRASS_HEIGHT=482
d.rast(5528) malloc: *** mmap(size=1206358016) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

G_malloc: out of memory

Other project  locations, set at 10m are okay.
