Gabe,

If you run cleanup while a script is running, you will kill the gplt
process and orphan the gf process. When you remove the message
queue (the script does this with the "ipcrm -q" command), you no

The script should be run when your scripts are not running.

Another bit of advice is to run each script in its own temporary
directory (such as shown in the csh examples using $$ to obtain
a unique process id for a working directory name) so you don't have
multiple scripts creating race conditions with ipcs and .nts files.

Robert (et al),

I am running the cleanup script that comes with gempak (once a day), and
it appears to me that the time at which my "gf" programs begin running
away is shortly after the cleanup is called from the cron.  Any thoughts
on why this might be?
