Follow-up Comment #2, sr #124729 (project xrootd): But what if two xrootd instances are running at the same machine? Or, even better, there is one already present and another one comes up later? I can not tell if this is the same "logical" instance being restarted or another server that will be doing something else just came up. I actually use triplet (ip4_addr, start_time, port) to uniquely identify servers as I was expecting that if two servers are started from init.d script they would similar, if not the same start times. _______________________________________________________ Reply to this item at: <http://savannah.cern.ch/support/?124729> _______________________________________________ Message sent via/by LCG Savannah http://savannah.cern.ch/
