I'm using ptpd 2.3.1 on FC22. On one server, I'm seeing "Offset above 1 second" errors, resulting in a clock step. It's only affecting one server in a VLAN where there are at least 10 other clients running the same config/version of ptpd2.
I see from the ptpd2.stat file that things hum along relatively fine until a certain point when the raw delay values get jacked. From there, it only takes a few seconds for the offset from master to spike above 1 second and cause the clock to step. This occurs a few times a day, but not at regular intervals. I don't see any contention from the master source (and this only affects one specific server--I'm not seeing the issue on any of the others in this datacenter). Hwclock doesn't seem to be out of whack, either. Curious if anyone can help me pinpoint the source of this clock drift.
Thanks!

It looks like chronyd was running on this system, and even though it wasn't configured to sync against anything, it was causing contention. While I did check with "systemctl status chrony.service" and saw the output "Active: inactive (dead)"I didn't check with the correct "systemctl status chronyd.service" which would have given me more accurate results.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Nice - I take it this resolved your issues? If you use the RPM build scripts that are part of PTPd, pre-install checks will check for the presence and status of ntpd and chronyd. Unless this is ptpd from FC, they have their own RPM spec standard so my specs didn't cut it. We will put this into the FAQ section, should one ever exist.
Thanks,
Wojciech

It looks like chronyd was running on this system, and even though it wasn't configured to sync against anything, it was causing contention. While I did check with "systemctl status chrony.service" and saw the output "Active: inactive (dead)"I didn't check with the correct "systemctl status chronyd.service" which would have given me more accurate results.
Nice - I take it this resolved your issues? If you use the RPM build scripts that are part of PTPd, pre-install checks will check for the presence and status of ntpd and chronyd. Unless this is ptpd from FC, they have their own RPM spec standard so my specs didn't cut it. We will put this into the FAQ section, should one ever exist.
Thanks,
