The Leap Second Is Here! Are Your Systems Ready?

Tmack writes "The last time we had a leap second, sysadmins were taken a bit by surprise when a random smattering of systems locked up (including Slashdot itself) due to a kernel bug causing a race condition specific to the way leap seconds are handled/notified by ntp. The vulnerable kernel versions (prior to 2.6.29) are still common amongst older versions of popular distributions (Debian Lenny, RHEL/CentOS 5) and embedded/black-box style appliances (Switches, load balancers, spam filters/email gateways, NAS devices, etc). Several vendors have released patches and bulletins about the possibility of a repeat of last time. Are you/your team/company ready? Are you upgraded, or are you going to bypass this by simply turning off NTP for the weekend?"

    Leap years = no problem.

    Leap seconds = kernel panic.

    Looks like Reddit's systems weren't ready for the leap second. It been down since around midnight (UTC). You'd think a site as big as that would be ready for such an event.

    Have you tried truing it off and turning it on again?
