[Freeswitch-users] FS core down soon after Forward Clock Skew Detected in windows

[Peter Olsson]

It might help if you start FS with "-monotonic-clock". This usually makes
the timing more accurate. However, on a VM you can never be sure.

Also, if I understand your first post correctly, when this error is shown,
it will bring down FS completely? If that's the case that must be reported
to Jira, since this is a bug (a crash is always a bug).

To make sure that timing is ok, always run on real hardware.
