Hi David,

Sorry I couldn't respond yesterday, but we just finished two day's of
meetings here at Unidata.

Everything is OK so far.  I have not heard if the paper I submitted
to CBMET has been accepted yet.

This is a bad situation that we need to understand and fix.

The question is what ADDE server is being accessed for the data used by
IMGDISP and SFCMG?

Robert's inquiry was about a decoder hanging.

What are the names of scripts that are hanging?  Which account are they
running out of?  Can I get on to troubleshoot?

I am glad to hear that having a link to CPTEC is proving to be useful
to you.  Your observation that having another site to talk to about
issues being useful is exactly what we mean by community building.
Getting folks talking about common needs and issues helps build a
strong community that can easily be extended to others if the exchanges
are made accessible.  This is the concept behind our inquiry tracking
system, a system that makes available the transactions between our User
Support and educators/researchers at sites available online.

Anyway, back to your problem.  If the scripts that are hanging are run
out of the 'mcidas' account on brisa, I should have login information.
If they are being run from a different account, then I need the login
information in order to troubleshoot.  Also, I need the names of the
scripts that are hanging (if not all).  Lastly, I assume that the
scripts are being run out of cron; is this true?

Cheers,

Tom
