Hi Kern,

If you cant access it, this info is given:
Workaround:
This error is normally transient and can be safely ignored. The NTP program will restart.
Eventough it looks there is not much to for now, maybe you could give us some info about the following
What kind of NTP server you have configured and if you generate a lot of load / jitter on your VMs
(also if you did any overbooking). How long does it take after a reboot that the warning shows up again?
Did you try to configure a different ntp server (check out ntp.org for example for available ones for your region)
