[GRASS-user] r.flow Terminates With Error

[Rich Shepard]

   I had no problems running r.flow with in the input elevation map resolution
of 5m x 5m. However, now it won't run (even with the -m switch) on a DEM
with 3m x 3m resolution:

GRASS 6.4.0svn (Oregon):/usr4/grassbase > r.flow -3m elevin=aber3m
aspin=aber3.aspect flout=aber_flowlines lgout=aber3.flowlength
dsout=aber3.flowdensity --o
WARNING: Vector map <aber_flowlines> already exists and will be overwritten
ERROR: G_calloc: unable to allocate 16690 * 8 bytes at alloc_cell.c:83

   That's only 133520 bytes of memory to be allocated.

   Have I done something incorrectly?
