[ncl-talk] Segmentation fault

[Gus Correa]

Hi Guilherme

I guess the computer may have run out of memory, specially if your arrays
are large,
because other processes may be competing with your ncl script.
Maybe the computer was less heavily used, when you ran the script
successfully.
If it is Linux, you can monitor the memory use in a separate terminal
window with top or htop.

I hope this helps,
Gus Correa
