Looking at the same problem for a long period of time tends to make one not see 
things that in hindsight turn out to be clear.  Been there, done that!

Sounds logical to me.

The BIG question is why dcgrib2 can't write to one or more files?  Since GEMPAK
logging is working, it means that the ~ldm/data/gempak/logs directory is 
by the user running your LDM (presumably 'ldm').  It would seem logical (but not
necessarily absolute) that the ~ldm/data and ~ldm/gempak directories are 
by 'ldm'.

Questions and Comments:

- first, where is ~ldm/data?  What I mean is: is a "real" directory under ~ldm,
  or is it a link to a directory on another file system?

- next, I would verify the read/write/execute permissions on ~ldm/data, 

- next, please send a long listing of the contents of ~ldm/data/gempak

- it would be helpful to see at least some of the log file for the GEMPAK 
  that is logging the most errors

The last possibility is you giving us a login to your machine as the user 'ldm' 
so we
can look around for anything that looks amiss.
