Follow-up Comment #1, sr #124729 (project xrootd): Actually, that is not correct. Each packet has the time that the server was started. If aa packet contains a time that differs from the previous packet, then the server was restarted. You use the start time with the dictid to form a unique ID across all time relative to that server. _______________________________________________________ Reply to this item at: <http://savannah.cern.ch/support/?124729> _______________________________________________ Message sent via/by LCG Savannah http://savannah.cern.ch/
