19990923: AVN model output

Wayne,

Looking at the stats files from your computer (you'll find these in
~ldm/logs/*.stats) which the mailpqstats program sends here,
I see that your latencies have been exceeding 1 hour for the HDS feed-
which should be accompanied by RECLASS statements in your ldmd.log file.

The RECLASS statements mean that your queue has fallen over 1 hour behind,
and so has jumped ahead in hopes of trying to catch up to present. As
a result, you will lose data when those jumps occur.

The data should already be purged out of Washington's data queue since it
is past several hours old- so they will no longer have it in their data
queue.

I have posted todays AVN thinned grib files at:
ftp://ftp.unidata.ucar.edu/pub/chiz/99092300_AVN.wmo  & 99092312_AVN.wmo

I will CC Robb Kambic on this message to see if he has any suggestions for
you
as far as improving your data latency.
