I have scoured the mailing lists for answers, so I appreciate it anyone has
ideas here...

* Running Gempak 7.1.1 + LDM 6.12.6 on a Debian 3.2.63 machine.  Machine
was wiped with new OS installed last week.

* Both programs were installed from source on the machine in the past few
days.  Make.out files show no obvious errors.

* LDM w/ noaaport is running and ingesting data just fine.  Using the
default pqact.gempak that came with Gempak.

* PROBLEM:  Some of the decoders are failing.  Log entries look like this:

*  Other decoders such as dcgrib2, dcmetr, dcuair are performing just fine.

*  I run a second server with identical hardware, but older OS (Debian
2.6.32) and older Gempak (6.4.0).  Newer LDM (6.12.6) is installed.  That
machine runs all decoders fine.

*  If I copy executables from other machine (LDM bin, or Gempak decoders,
or both) I get no change.

*  I attempted to compile Gempak with standard make file, and with the
Ubuntu version.  No change.

*  I am beginning to suspect the newer OS, or perhaps one of the
libraries.  Just not sure which one would cause these symptoms.

Thanks for any help.
