Tom,
I reset my time update to use ntpd I noticed the that at 0z my latency was
almost
nil, then as the day progressed I would hit a high of almost 6 seconds, and
then fall
right off to nil again at 0z .. I found the root CRON and seen the ntpdate
daemon running
at 0z everyday so that solved that .. my system is now using ntpd.
I noticed that this arbitrary problem stopped happening at 21z the last time
I have seen it.

No I am not relaying Level 3 data, it is filed on this server and
then I have 12 people that use a desktop Level 3 program to view the
data.
>If you are not relaying using the LDM, what are you referring to by

I stop getting data, its like my upstream LDM's have stopped receiving it
themselves, I get no error in the ldmd.log, just the data is not there, the
only thing
I see in the log for the 15-20 minute period is the EXP and DDPLUS data,
and a handful of NEXRAD data, no where near the normal.
>What is your pqact pattern for processing the Level
>3 products you are receiving?
NEXRAD ^SDUS[2357]. .... ([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(...)(...)
FILE -close data/gempak/nexrad/NIDS/\5/\4/\4_(\1:yyyy)(\1:mm)\1_\2\3
of coarse the copy and paste took out the tabs but they are there.
I doubt is its related or not, but when Gerry chimed in and
said he would re-start bigbird, that is about the time the
problem corrected itself.
now that I look at this
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NNEXRAD+level3.michiganwxsystem.net
it is showing up the spikes in latency upwards of 800 seconds,
as I compare it with Tylers machine
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NNEXRAD+level3.allisonhouse.com
he is showing the same odd spikes at the or close to the same times I am
now its on bigbird as well
http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?NNEXRAD+bigbird.tamu.edu
so it looks like it was very hit and miss, and coming from before my
upstream hosts ...
Or am I not reading these correctly ??
