Hello
I am running vpp (latest stable/1908) on kubernetes pod. Sometimes I get a
warning
> clib_time_verify_frequency:249: Rejecting large frequency change of
> +infinity%
WIth the warning vpp stops sending and receiving any packets of all
interfaces. This warning logged by vpp a lot of times by each run.
Removing next block of code helps, but I think it is not correct way to
resolve this issue.

Could you please help to find a root cause of an issue and resolve it.
Thanks
