papagayo is doing fine. I say this because I was working on papagayo a
good bit of time yesterday/last evening, and it was running smoothly.
I think that the problem is the link speed between papagayo and your
machine.  I noticed that when I shut down the LDM on papagayo (I did
this after building McIDAS with my latest addendum) the rpc.ldmds that
were feeding your machine would take a very long time (like over 15
minutes) to exit.  This is a sure sign of a very slow connection
between the feeder and the feedee.

Right, but other sites downstream of papagayo are not having problems.

I noticed that papagayo is feeding model data (HRS) from UIUC and that
UIUC was feeding model data from motherlode.  If UIUC was not feeding
HRS from another server, there should have been no model data for
a large fraction of the day yesterday.  UIUC should have switched
their feed, but they did not.  We will be addressing this tomorrow.

Yes, it is.

Ditto, but your link to it is slow.

Hopefully, your network connection to papagayo will clear up soon.

Thanks for getting back to me. All that I can think of to say right now
about the slow connection is that it sucks!  :-)

It seems I am in the "catch-up" mode as far as data coming back in. At
least I I think I am. I have not gotten any IR type images since
13Z....still. I am starting to get some 1km vis imagery on a
semi-consistent basis but it is still running 60-90 minutes behind real
time. As is the individual radar data but at least it is consistently
coming in and I think it is trying to "catch-up".  I find it odd that I
am not receiving any IR type of imagery from either the EAST or
WEST-CONUS views yet I am getting the 1km VIS from the EAST-CONUS view
albeit is behind actual time. I would think the smaller sized IR images
would be able to make it across as opposed to the much larger vis

If it is my connection is slow then I guess I can't do anything about
that. Like you said hopefully the connection will work itself out soon.
One question I have for you that has been "bugging me" lately is when I
do an ldmadmin stop command. You had said befoe that sometimes it takes
awhile for the processes to stop and to wait before shutting down the
computer because that would be bad. You said do the command ps -u ldm to
check on the processes. Well, it seems just about everytime I do that
all the processes are stopped immediately. Is that normal or should
there be some lag time in there? It was something that was in the back
of my mind and I thought I would ask. 

Here is my last hour's (roughly) worth of log entries. Maybe this will
be of some assistance in case there is something else going on or if you
see something out of the ordinary.
