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. >I am not familiar with your setup. Are you relaying the Nexrad Level >3 data to other sites using the LDM? 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 >"all the sites just stop updating"? Updating where and how? 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 ?? -Jeff
