[GEMPAK #DPN-938735]: no data written by dc* progs

Hi Eric,

I am jumping in here since it was I who first fielded questions related
to GEMPAK decoders not writing their output files.  I helped two different
users who were running RedHat Enterprise Linux with this problem, and both
problems disappeared as soon as IPv6 support was turned off.  Your
experience may differ given that you are running under Debian, and the
others were running under RedHat Enterprise.

To reinforce what Michael mentioned in his original reply to you, we don't
know exactly how or why disabling IPv6 support should enable writing of the
GEMPAK decoder output!

The following web page may be of some help, or, at least, be provocative:

I just took a quick look at your log files.  The messages being written to
the log were much the same if not identical to what the other users I alluded
to above were seeing.  I have a feeling that the last line in the following
snippit is trying to tell us why the problem is happening:
