I want to ask about this “io timeout” that appears on csv log, i see the pontuation droping and connection dropping. What should be done at the server side to skip this errors? I’m operator of a stratum 1 NTP server that is a Raspberry PI 3 without original crystal oscillator (19.2MHz), we has connected the crystal input at one DDS that is connected to a local time scale UTC(LRTE) and is traceable in BIPM time department: https://goo.gl/oSzRrF
the server: https://www.ntppool.org/scores/22.214.171.124
big drops was due server disconnection and settings changing because of upgrades, but, this “io timeout” always, always happened.
