Hi Justin, I just reviewed the real-time stats from the 3 toplevel CONDUIT machines at the WOC, and two of the machines continue to show virtually identical volumes of data, and the third shows consistently less data: Machines that are virtually identical: ncep-ldm0.woc.noaa.gov http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+ncep-ldm0.woc.noaa.gov ncep-ldm1.woc.noaa.gov http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+ncep-ldm1.woc.noaa.gov ncep-ldm2.woc.noaa.gov should show higher data volumes, but shows consistently less: ncep-ldm2.woc.noaa.gov http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_vol_nc?CONDUIT+ncep-ldm2.woc.noaa.gov Since there was no change in data volumes since you killed the "hung" gribinsert process on ldm2, I am left with the impression that it is not getting the same set of "operational" data that ldm0 and ldm1 are. Can you check into this again? Now for some good news: It appears that the parallel NAM data (i.e., firewx products) data peaks occur at different times than the overall peak in "operational" CONDUIT volume. This means that the addition of the products is not having as detrimental an effect as they would if the volume peaks were at the same time. This, in turn, should mean that the effect on the LDM queue residency time does not demand an immediate increase in LDM queue size (which would require an immediate increase in system RAM). HOWEVER, the fact that the minimum age of the oldest product in the LDM queue is 0.5 hours (30 minutes) is worrisome. We prefer that IDD toplevel, data source, and relay machines maintain a minimum of 1 hour of data in their queues. It is, therefore, our recommendation that more RAM be added to each of the 3 toplevel CONDUIT machines (at least 2 GB, preferably 4 GB or more) and their LDM queues be increased correspondingly (i.e., at least 2 GB but preferably 4 GB). An increase in LDM queue size will provide for more "elasticity" for the data flow and allow for more products to be easily added.
