Gilbert,

The log messages cover about 1.5 minutes rather than 5 minutes.

I didn't see "unidata.ucar.edu" in the messages. Would you please send me the 
output of the command "fgrep unidata.ucar.edu var/logs/ldmd.log" if it's not 
too large. I'd like to see any messages from the downstream LDM that's 
receiving NEXRAD3|WMO products from idd.unidata.ucar.edu.
