frequency error exceeds tolerance 500 ppm Sloatsburg, New York

Perhaps the host machine should deliver accurate time and everyone should rely on that? With modern technology, is it possible to permanently stay in sunlight, without going into space? Hot Network Questions Trouble understanding charging capacitor on bridge rectifier Is 'if there's any' grammatical in this sentence? The ticks from the host probably only 'ticks' the clock.

all these messages in my log files. Well I wondered what relationship the clock on a VM has to that on the host machine. The host clock is probably never touched by the UML-clocks. Thank you!

If the difference exceeds 500 parts-per-million (0.0005%) over the synchronization interval then the log message appears. The replica on the same network with an identical ntp.conf file doesn't have these messages in the current log. We Acted.

Maybe it just a simple misconfiguration? Searching for time_kern.c in Google gives me some code for 2.6.17 (wrong version probably but anyway).

If you have any questions, please contact customer service. For example, NTP, can set it or adjust it with no problem. I would guess that ticks from the host are lost sometimes, maybe when the load is high? There were only two notable changes to this system recently.

Peter Collinson: Well I wondered what relationship the clock on a VM has to that on the host machine. We would have thought it pretty astonishing a few decades ago the idea that affordable systems could make visible the need to make up the tiny difference between atomic clock time You need to set your time to be closer to the time server's time. Perhaps the host machine should deliver accurate time and everyone should rely on that?

ntpd will only sync the local time if it is relatively close to the time server. Hmm.

This may have happened because the time was not set before starting ntpd, because the server stepped after ntpd was started, because you are running ntpd with the "-x" option, because

awilliams 2006-05-12 11:06:39 UTC #6 It is an irritation more than anything else ... Several root causes are possible for example, incorrectly working timesources in the system. My ntp.conf uses 0.uk.pool.ntp.org, 1.uk.pool.ntp.org, 2.uk.pool.ntp.org. I have managed to reduce some of the crap.

You should also make sure that the ntp servers you are syncing with are relatively close. The fact that it's making the clock leap in time - is a bad thing. It could be broken hardware.On 10 September 2015 at 14:05, Prasun Gera wrote:Thanks. tlundqvist 2006-10-24 17:28:53 UTC #11 Peter Collinson: The clock on my VM is drifting wildly - such that ntp is forcing periodic time resets.

The timesource can be changed, different timesources could be more reliable in the system. Maurits van Rees dewart 2006-05-02 19:47:25 UTC #5 I think this is an 'expected' error on VMs: I don't think it's harmful and it generally doesn't seem to stop the VM Are all the VMs on the machine running ntp actually fighting each other?

Should I be running ntp - isn't it possible that my reference clock differs from that used on the virtual machine host - or on some other VM? Register If you are a new customer, register now for access to product evaluations and purchasing capabilities. This will only fix situations where the offset between ntpd computed time and internal clock is big, but the internal clock is working reasonably accurate (so can be compensated by ntpd): Not the answer you're looking for?

This will only fix situations where the offset between ntpd computed time and internal clock is big, but the internal clock is working reasonably accurate (so can be compensated by ntpd): What should one do? However, if I go back to a week, I see similar messages there too.  The ping to public ntp servers varies from to a few ms to ~50 ms. I'll save you the math but this works out to about 3.15 seconds per 15 minutes + ntp overhead.The solution is simple:  Check you're running  BIOS:      version 1.0.19  kickstart: version 5.0(4)
