Alan,

That's correct product construction SAUS80KWBC0414.wmo.  

Something to check is that the ldm has write
permission on dir /npraid/noaaport/data/   Also, if this was a binary
installation and LDMHOME is not /usr/local/ldm, then a link needs to be
made /usr/local/ldm.  Detail instructions at:

This is because hupsyslog is not suid root. Instruction at:

Start the ldm from the command line, ie

%  bin/rpc.ldmd -vl - -q data/ldm.pq etc/ldmd.conf

Look at the log messages on the screen.
