[ferret_users] partionned files, **ERROR Ferret crash; signal = 11

[Brockmann Patrick <Patrick.Brockmann@xxxxxx>]

Hi ferreters and ferret team,

I am dealing with spatially partionned files coming from a parallelized 
model.

Rather than rebuild the global field from the different partionned files,
I have tried a script that overlays the different parts on a global basemap.
It works and finally represents the desired field on the global world map.

Unfornuatelly, I get an error when I open partionned files that have a 
lot of variables (> 250).
After the overlay of the 184th files, I get :
**ERROR Ferret crash; signal = 11

Each partionned file size is 140Mo.
Strangely, It works when I open partionned files that have less variables.

So I suspect that the memory clearance made by the "cancel data" command 
is not well done
and ferret may conserve in memory things that causes the crash.

The all partionned files size is 34Go so it is not easy to distribute 
them for testing.

I am looking for any idea that might help me to solve the problem.

Attached is the script and bellow the call and the error.
