I am running a Raspberry Pi 3 as a weather station at home, and it will crash every couple of days. When I restart, the only clue in syslog is:

Apr 15 13:35:27 weather systemd[642]: Time has been changed
Apr 15 13:35:27 weather ntpd[471]: receive: Unexpected origin timestamp 0xde7ce04f.465baf92 does not match aorg 0000000000.00000000 from server@ xmt 0xde7dc58f.70ff4546

/etc/ntp.conf is pointing to pool.ntp.org.

The server has a static IP address on an internal LAN.

Perplexed. Any ideas why this is happening?

  • The joys of systemd? Will you have some Poettering with that? github.com/systemd/systemd/issues/1143 – Gerard H. Pille Apr 16 '18 at 10:59
  • Kernel patching? Eek! I thought I'd left that behind when I shut down my last Slack server! – Darren Matheson Apr 16 '18 at 11:52

    I just wanted to point out that systemd has had problems with time changes before. Perhaps use another pool? – Gerard H. Pille Apr 16 '18 at 12:06
  • I have an ESXi host and a dozen VMs on the same network (and they have kept time flawlessly for two years). I might point it at one of them.. – Darren Matheson Apr 16 '18 at 12:33
  • Would you trust an ESXi with something as precious as time? ;-) Perhaps faelix.net should change to failix.net. Are they part of an NTP pool? – Gerard H. Pille Apr 16 '18 at 12:38
