Mike, 

Please try feeding from thelma.ucar.edu

Let me know what you see.

What version of the LDM are you running, I do not see your machine on our
real-time stats page so I suspect 5.1 or lower. It is a very useful tool
for diagnosis, so if you have not upgraded, it would behoove you, if you
have upgraded..please place this :

exec    "rtstats -h flip.unidata.ucar.edu"

in your ldmd.conf file thusly:

####
#
# Programs that share a queue with rpc.ldmd
# are started by it and are in the same process group.
#
exec    "pqbinstats"
exec    "pqact"
exec    "pqact -f NMC2|SPARE /opt/ldm/etc/pqact.conduit"
exec    "pqact -f NEXRAD /opt/ldm/etc/pqact.nexrad"
exec    "xcd_run MONITOR"
exec    "rtstats -h flip.unidata.ucar.edu"


Let me know what you see after flipping to thelma...

FYI- real stats are at:

http://www.unidata.ucar.edu/staff/chiz/latency/rtstats/

index1.shtml is by feedtype and
index2.shtml is by site

Cheers,

-Jeff
