MySQL High Load / Other Issues - Leap second bug

After struggling with a sever that was acting up, i did some investigating and found it to be related to a recent leap second that was added on June 30th. On Saturday midnight Greenwich Mean Time (GMT), an extra second was added to the Universal Coordinated Time (UTC). According to some news reports the Linux kernel has a bug in how it handles leap seconds.

The fix was simple:

 service ntpd stop  

date -s "`date`"
service ntpd start
