Kenyon, Thank you. I disabled Pacemaker, however, this didn’t help much. In the end I also had to download and install the latest version of NTP. This has resolved the issue. In my opinion, Apple should fix what they broke when they distributed 10.9.1 and 10.9.2. Maybe 10.9.3 will resolve the issue, but I am not counting on it.
