Re: 20030929: request to upgrade your LDM from 6.0.10 to 6.0.14

After a lot of pestering, I got my System Admin to install 6.0.14 on a system
earlier today for testing purposes.  I've run into one problem.  Program
"dcmetr" likes to seg fault a lot, as in several times an hour.  Our version of
GEMPAK is from 2002, so I'm hoping a GEMPAK software upgrade will fix the
problem.  I've put in a request to your Admin people for the upgrade.
