I = have noticed the occasional interruptions in Zabbix charts in the past on previo= us FreeBSD versions, but since upgrading to 11.2-p0, the problem has gotten to= the point where the clock freezes entirely and blocks disk IO and various processes. Even the "data" command refuses to increment (see attached file). I can probably stop ntpd entirely, but it would be nice to get some possible debug type commands to run so that I can try get to the bottom of why ntpd = is stopping the clock on this one server. I used to have LOCAL(0) stratum 10 l= ocal source enabled, but disabling this had no effect. I'm open to suggestions!
