[LDM #VXF-693432]: Trying to request NEXRAD2 data from Unidata

John,

It looks like host nowcast-station-temp.mdl.nws.noaa.gov has three separate 
requests for NEXRAD2 data:

    $ uldbutil | fgrep nowcast-station-temp.mdl.nws.noaa.gov | fgrep NEXRAD2
    12359 6 feeder nowcast-station-temp.mdl.nws.noaa.gov 20130701125602.158

Each request is being honored at our end. For example

    $ fgrep '[4590]' ldmd.log

    Jul 01 15:36:11 uni19 nowcast-station-temp.mdl.nws.noa[4590] NOTE: Exiting

The downstream LDM-s on nowcast-station-temp.mdl.nws.noaa.gov appear to 
reconnect approximately every 7 hours.

As far as I can tell, everything's working as it should.

You can check for the last 10000 seconds worth of NEXRAD2 data-products in your 
product-queue with the command "pqcat -vl- -f NEXRAD2 -o 10000 >/dev/null".
