(works fine for me on 6.0beta2)

at which point in the script? Here it takes a couple minutes to run,
long part is duing the v.surf.rst step but no runaway memory issues.
run "top" in another window to watch what is going on?

What is your region set to?
try 'g.region rast=(map)' first?

what is the output of "g.region -gm" ??

I've just added some more error checking in CVS, can you update and try
again? maybe uncomment "echo RES=.." line?
(It won't fix your problem but will stop the script if this step fails.)


- In the script we should temporarily zoom to the raster limits with
g.region first?

- I wonder if we should look at using a bigger r.buffer/r.grow area to
get the slope etc at the edges of the hole a bit more correct?
