Doug, Thanks for the update -- ultrazone must be near the limit of TCP buffer tuning. Can you change your CONDUIT feed requests from atm.cise-nsf.gov to idd.cise-nsf.gov? At some point in the very near future, atm will not accept LDM connections but rather will serve as an aggregation system for idd.cise-nsf.gov Thanks, mike > Mike, > > The tcp modifications led to higher latencies and missing data from ECMWF. > I've returned the system to the previous values this morning. > > http://www.unidata.ucar.edu/cgi-bin/rtstats/iddstats_nc?EXP+ultrazone.ucar.edu+LOG > > Doug Ticket Details =================== Ticket ID: SOD-321591 Department: Support IDD TIGGE Priority: Normal Status: Closed
