Since upgrading my jail server to 11.1-RELEASE, the clock occasionally
jumps backwards by 5-35 minutes for no apparent reason. Has anybody seen
something like this?

* Happens about once a day on my jail server, and has happened at least
once on a separate bhyve server.
* The jumps almost always happen between 1 and 3 AM, but I've also seen
them happen at 06:30 and 20:15.
That's the window when the period scripts are run which if you have a
default configuration and a lot of jails will put the system under a lot
of stress.
* I'm using the default ntp.conf file.
Are you running ntpd inside the jail or on the jail host? On my jail
systems (which are 10.3 and 11.1) I run ntpd out the jail host (outside
all jails) and not inside the jails and the jails then get the accurate
time as the underlying host has accurate time.
