I am running ntpd with DCF77 receiver. Ntpd sometimes crash, when signal is bad, but not often. Today I noticed multiple crashes of ntpd and also I have seen my one of my DCF77 clock had bad time. It was some time forward (half hour-hour?).
Later alert from pool.ntp.org monitoring had come, that server is not reachable - but ntpd was running (it have auto-restart). Graph is really strange
I can’t see any ~1800 values which are in graph in data https://www.ntppool.org/scores/184.108.40.206/log?limit=200&monitor=*
DCF77 logs dcf77logs.de - Dcf-Daten aus DcfLog_20210918.dcf does not show any problems.
Anybody else running ntpd with dcf77? Share your experience.
