Steve:

Thanks for looking at our LDM on "Halo".  But, it's still not right.  I'm 
looking at the latest east-coast IR at about 8 pm EDT on 7 October (0000 
GMT on 8 October).  The loop starts at 0815 GMT and loops hourly to 1515 GMT 
on 4 Oct then jumps to 1615 GMT and 1815 GMT on 6 October then back to 
the beginning of the loop.  So, the loop is not up-to-date, nor in proper 
sequence.

Could you please take another look at Halo's LDM and see if you can 
restore order.

Thank you!

Sincerely,

Prof. Ward Hindman
CCNY

Hi Ward,
     I was away, but I've heard our University
had network problems on Oct 4 and 5.
Apparently the internet connection was
very slow (maybe even intermittent).
We've still got entries like:
./ldmd.log.2:Oct 06 20:08:25 redwood halo(feed)[6240]: pnga2area Q1 UW 213 GOES-
8_IMG 6.8um 8km 20001006 1915: RPC: Timed out
./ldmd.log.2:Oct 06 20:08:25 redwood halo(feed)[6240]: pq_sequence failed: I/O e
rror (errno = 5)
./ldmd.log.2:Oct 06 20:08:25 redwood halo(feed)[6240]: Exiting

in our ldmd.log file if that helps you or steve
diagnose the problem. It might be possible
that your product queue got currupted while
we were having network problems. Perhaps
recreating the product queues would get data flowing to
you again.


traceroutes to halo look pretty good, *except* at the
very last step...

Since we appear to be both on applied theory, network
connections between our machines *should* be good.
Perhaps there are local problems at ccny?

If you (or support@unidata) ever want to look
at redwood ldm logs, or traceroute a host from our machines,
you can use our web page
