Wayne,

You can use the notifyme command to check what products your upstream
is receiving:

notifyme -v -l - -o 3600 -f MCIDAS -h grayskies.atmos.washington.edu

It appears that currently, that machine is not receiving any MCIDAS products.
This should not have anything to do with the message below.

>> 
>> request      MCIDAS  ".*" upstream_feed_machine_name
>> 
>> This enables all images to be sent to the relay.
>> 
>> The request line for IDD leaf nodes can be refined to request only
>> PNG compressed imagery:
>> 
>> request      MCIDAS  "^pnga2area Q[01]" upstream_feed_machine_name
>> 
>> Leaf nodes should only change their MCIDAS request lines if they have
>> installed and configured their pqact.conf files for pnga2area.
