Gilbert,

Now that's a log file! :-)

I didn't see anything in the log file to indicate that the LDM on Weather2 was 
ever requesting data-products of feedtype "NEXRAD3|WMO" (which is the same as 
"IDS|DDPLUS|HRS|NNEXRAD") from "idd.unidata.ucar.edu". Can you find a "Starting 
Up" message to that effect in the earlier log files? The command 

    fgrep 'Starting Up' `ls -tr ldmd.log*` | fgrep WMO | fgrep 
idd.unidata.ucar.edu | tail

should do it.

I did notice partially overlapping requests regarding the FNEXRAD feedtype. You 
should vet the LDM configuration-file regarding that feedtype. Feeds should be 
disjoint or identical: partial overlaps in the feedtype/pattern specification 
can result in missed data-products.

If you'll send me Weather2's LDM configuration-file I'll be happy to take a 
look at it.
Regards,
Steve Emmerson
