That's a huge offset, probably enough to 'throw' ntpd. Can I suggest:

 

  • a) Remove 10.13.1.12 as its simply a slave/client of .11.

     

  • b) Manually change the date/time so its a bit closer to that of .11 so the offset isn't so large

     

  • c) The jitter also seems very high too, is the network path to .11 stable? Is the firewall its passing through under high load?
