Your peaks of 40 GB is 11 GB/hr larger than what is being relayed by
idd.unidata.ucar.edu. This does indicate that your LDM queue size is
too small -- the extra volume reported is most likely being caused
by receipt of "second trip" products (ones that were received, were
deleted from the queue and then received again).
But, a suggested queue size of 83 GB is _way_ too large. A queue size
of 40 GB would be more like it.
I am sure that Steve will chime in with other observations...
Cheers,
Tom
