Anyone Besides Zune Owners With New Year's Crashes?

aputerguy writes "My Fedora 8 Linux server crashed sometime between 18:59:40 EST (GMT -5:00) and 19:00:00 EST (GMT -5:00) on Dec 31, 2008 which remarkably corresponds to within at most 20 seconds of the New Year in GMT. I have been running this same hardware non-stop for more than six years and other than the occasional reboot for kernel (or distro) upgrades, it has not crashed more than 1 or 2 times in 2237 days of cumulative uptime. Nothing other than background processes were running at the time of the crash. Could this be a coincidence or was there some 2008/2009 rollover issue going on here? Has anyone (other than Zune 30GB owners) noticed similar year-end issues with their computers or electronic devices?"

The motherboard or some other hardware component is beginning to fail, and the server will start crashing more frequently until that component dies completely.

This epoch is the beginning of the last 400-year cycle by which leap-years are calculated in the Gregorian calendar. The last year of this cycle is the only one divisible by 100 that is a leap-year, which was the year 2000, and which was followed by a new 400-year cycle beginning with 2001. 32-bit versions of the Microsoft Windows operating system count units of one hundred nanoseconds from this epoch

  32. NTP and the leap second by Charles+Dodgeson · · Score: 4, Interesting

    A surprising number of NTP servers didn't add the leap second correctly. On the mailing list for pool.ntp.org contributors, it was reported that at just after midnight UTC that about 158 servers in the pool (about about 2000) were reporting times that were around 1000ms off. A few hours later it was only 13 that were doing that.

    My own (stratum 3) NTP server got confused and declared that it couldn't determine the correct time. Some of its sources were 1000ms off from others. Given enough time, NTP will sort itself out, but I intervened manually by ditching the upstream servers that hadn't gotten it right.

    If enough NTP servers were temporarily in the state that mine was in (was so unsure of itself that it wouldn't serve time to clients) then I could imagine some process that tries to sync the time and fails because ntpdate doesn't return anything useful.

      Failing to update surely shouldn't be a matter of crashing, however. Network services do go down; it's something you plan to cope with.
