Celia, Yes, the times are latency for a product. You have a machine "clamp" that is feeding from both thelma.ucar.edu and f5.aos.wisc.edu as you see here: http://my.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?CONDUIT+clamp.rap.ucar.edu You also see that alost the entire volume yopu are receiving is coming via thelma, and very little via f5: http://my.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+clamp.rap.ucar.edu I suspect that your queue isn't large enough to hold 1 hours worth of data, and that periodically, you receive an old product from f5 that you already received from thelma, but has since been scoured out of your queue- so you receive it a second time from the redundant feeder. You can use the ldm program "pqmon" to show you the age of the oldest product in your queue. If this is falling below 1 hour (3600 seconds) and you are feeding from more than 1 host, you could receive a product that you had previously received but has since been scoured out of your queue to make room for new data.
