Apparently there are less than 52 MB of free memory left. The resulting

Maybe also use a larger step or less levels.
Markus,
Tried both. Still cannot complete the creation of contours from the
raster.
export GRASS_VECTOR_LOWMEM=1
time r.contour --overwrite in=highest_hit_2010 out=highest_hit_contours step=0.5

I created a mask of the raster DEM using the project bounds (which I set
as the computational region) yet it appears that the entire DEM coverage is
being converted to contours and failing.
Thanks,
Rich
