Leap second + Java + Linux fix (without reboot): /etc/init.d/ntp stop; date; date `date +"%m%d%H%M%C%y.%S"`; date; -- then restart java

Thank you! Was banging my head against the wall on RHEL6's tomcat. Went on Hacker News to stop thinking about it for a few minutes. Son of a bitch, the solution was right on the front page.

Even if you're not running java in your stack, it's worth a quick check on your servers. Our SoftLayer servers use an Adaptec RAID card and the monitoring software uses the JVM and will suck up all of your CPU. All of our MySQL/Cassandra/Redis/Kestrel servers needed to be bounced because they had RAID cards. Frustrating.

Has anyone seen this not on Ubuntu?

I saw this on my Fedora 17 laptop. Chrome started eating up 100% CPU and my laptop started getting really hot. I tried restarting Chrome, updating Chrome, etc. Nothing worked. Rebooting fixed the problem.

Surprisingly, none of my servers have had problems, but I don't run Java anywhere.

This is what worked for us. Credit to https://bugzilla.mozilla.org/show_bug.cgi?id=769972#c5
