'notifyme' is showing that ldm.meteo.psu.edu is willing to feed you.
Perhaps you did not wait long enough to see if it had products.

So, if you let your notifyme example run for a bit and do see products,
then it is likely that your LDM queue somehow got corrupted.  In this
case, you should delete it, remake it, and then restart your ldm:

ldmadmin stop
<wait for LDM processes to exit>
ldmadmin delqueue
ldmadmin mkqueue
ldmadmin start

We could snoop around if the above doesn't work.  We would need the password
for the 'ldm' account.

Tom,

I rebuilt the queue.  Looks like that did the trick!

Thanks for your help!
