Aha!  The file

/home/ldm/gempak-5.6/gempak/tables/pack/msfc.pack
was missing. That 'pack' directory was entirely empty. So I copied over the 'pack' files from another machine we have, and I'll see what happens.

Carl,

Your dcmsfc.log file shows a problem reading your $GEMTBL/pack/msfc.pack
file. In your pqact.conf file, you are setting GEMTBL to be
/home/ldm/gempak-5.6/gempak/tables.

Is the /home/ldm/gempak-5.6/gempak/tables/msfc.pack file readable by the ldm 
user
(asking here since if it was installed by a different user with umask not 
allowing
the ldm user, that would be a problem). If readable, double check to make sure
it wasn't modified.

Steve -
Thanks for the information. When logged in as 'ldm' I can make little test files in those two directories. 


Is your expected GEMPAK data directory ~ldm/data/ldm/gempak?<

Close.  It's actually ~/data/ldm/gempak

Here is my environment:

mds-ingest1:ldm> whoami
ldm
mds-ingest1:ldm> env

Carl,

The pqact.log  file you provided shows several sets of errors.
Besides the dcmsfc errors, you have numerous other perl decoders with
permission denied. This seems to say that the LDM user running
pqact can not write to $LDMHOME/data/ldm/gempak/ship and/or $LDMHOME/data/ldm

/gempak/logs.

If you do have data/ldm/gempak/logs/dcmsfc.log, then that file might give
some additional clues since you say that the logs directory is writable.

Is your expected GEMPAK data directory ~ldm/data/ldm/gempak?
Your pqact.conf patterns are relative to the LDMHOME directory
and that is the location you are using.

Unidata -
Can you help me figure out what this "Broken pipe" error means in the pqact.log file? 

^@May 25 20:15:12 pqact[15507]: pbuf_flush (8) write: Broken pipe
^@May 25 20:15:12 pqact[15507]: pipe_dbufput: decoders/dcmsfc-b9-a10000-ddata/ldm/gempak/logs/dcmsfc.log-eGEMTBL=/home/ldm

^@May 25 20:15:12 pqact[15507]: pipe_prodput: trying again
I have checked that the dcmsfc decoder is installed and executable in the decoders sub-directory. The log directories are writeable by ldm. 

I have attached the relevant files to this message.
