Ntp Tolerance
up vote 6 down vote accepted This means that the difference between your local time and the server you're syncing with has exceed ntpd's limit. ntpd will only sync the local time if it is relatively close to the time server. This is why Red Hat (as an example) uses ntpdate the first time you start the ntpd service to set the local time to be in the right ball park. You should also make sure that the ntp servers you are syncing with are relatively close. You can do these steps manually if you want (e.g. you're not running Red Hat which includes the ntpdate step in it's restart script): # /etc/init.d/ntpd stop # ntpdate

Favorite Rating: NTP time synchronization issue on SUSE Linux Enterprise Server 10 Service Pack 4 running on VMwareThis document (7010716) is provided subject to the disclaimer at the end of this document. Environment SUSE Linux Enterprise Server 10 Service Pack 4 Novell Open Enterprise Server 2 (OES 2) Linux Support Pack 3 NetIQ eDirectory Situation On virtualized SUSE Linux Enterprise Server 10 Service Pack 4, time synchronization using Network Time Protocol daemon (ntpd) is not properly working reporting major clock drift: # cat /var/lib/ntp/drift/ntp.drift -500.000 and several frequency errors in the ntp log file: # cat /var/log/ntp[...]9 Jul 11:06:37 ntpd[466]: frequency error -512 PPM exceeds tolerance 500 PPM 9 Jul 11:07:43 ntpd[466]: frequency error -512 PPM exceeds tolerance 500 PPM 9 Jul 11:08:46 ntpd[466]: frequency error -512 PPM exceeds tolerance 500 PPM 9 Jul 11:09:49 ntpd[466]: frequency error -512 PPM exceeds tolerance 500 PPM[...]If on your system is running eDirectory, you could also have verified a time synchronization issue with the command "ndsrepair -T" The issue has been verified on systems running kernel version 2.6.16.60-0.97.1 on VMware. Resolution Solution:Please update to kernel 2.6.16.60-0.99.1 or later.Workaround:Disable the Time Stamp Counter using the kernel parameter "notsc". In order to do this, add "notsc" to the kernel line in the file "/boot/grub/menu.lst". An example below: kernel /boot/vmlinuz-2.6.16.60-0.97.1-default root=/dev/sda2 vga=0x314 resume=/dev/sda1 splash=silent showopts notsc Then reboot the system and verify if the issue is solved.
