Justin,

I think I found the problem.  It's related to the addition of the
command-string to some of pqact(1)'s log messages.

Would you be willing to try another version?  If so, then replace your
LDM 6.4.3.0 with

    ftp://ftp.unidata.ucar.edu/pub/ldm/ldm-6.4.4.0.tar.Z

If it fixes the extraneous logging messages, then I'll release
it as version 6.4.4.

Regards,
Steve Emmerson

I passed this along to Jeff and Scott who work with the decoders...here 
is their response:

---
The GEMPAK-based decoders do not close the input data stream. They read 
from standard input. After a timeout (no data has arrived in X amount of 
time), the decoder does shut down. I don't know if the LDM is aware of 
the shut down or if the pipe remains open from the LDM end.

Hopefully that answers your question,

Justin
