> Mike, can you share me your kernel version and which Linux distro do you use? 2.6.32-504.el6.x86_64 AKA RHEL 6.6 Happened on centos 7 and 6.5 too. #cat /var/lib/ntp/drift -248.869 About 20 secs a day (constant) Its not a new problem I had this in other distros and other kernels. I would say its environmental but not just my environment. Confirmed with Olaf on SUSEvariants back in 2012 but never came to anything see enc email --------------------------------------------- > > KY, can your team have a look at this? > > Vijay, have we done time stability test in the recent past.

Olaf, on sles11 > sp2, were you running NTP and how much was the drift. sles11sp2: uptime 23:45 hours, its 38 seconds ahead 12.2: uptime 1 day, 5:17 hours, its 47 seconds ahead ntpd is not running in both guests. > Also, what was the host in this test. The host is an uptodate w2k8 r2.
