Your LDM log file shows that Nitro started receiving data from Usgeo1 at Feb 15 
22:15:30. It then lost contact with Usgeo1 at Feb 19 20:34:19, tried to 
reconnect several times, and finally succeeded at Feb 19 20:35:44. It then lost 
contact (again) at Feb 19 20:59:35 and reconnected at Feb 19 20:59:37. This 
last connection is logged in the LDM log file on Usgeo1.

All in all, the log files show the LDM doing exactly what it was supposed to: 
reconnecting and starting where it left off when a network outage occurs.

Does the pqcat(1) utility show that the data-products you want are in the 
product-queue? For example

    pqcat -vl- -f EXP -p 'multi/Reflectivity_-10C/' >/dev/null

(Whether or not this works depends on the rate that data-products arrive, when 
the specified data-products arrive, and the size of the product-queue.)
