July 1 2012 Linux problems? High CPU/Load? Probably caused by the Leap Second!

(Update posted, see below)

As posted in multiple places around the web:


/etc/init.d/ntp stop
date `date +"%m%d%H%M%C%y.%S"`

Red Hat

/etc/init.d/ntpd stop
date `date +"%m%d%H%M%C%y.%S"`


This first manifested itself for us in our Java stacks — all of our (dual processor) Tomcat servers were running at a load of 30-40. ¬†However, this is a known (and fixed) kernel bug:;a=commit;h=6b43ae8a619d17c4935c3320d2ef9e92bdeed05d

Apparently, simply forcing a reset of the date is enough to fix the problem:

date -s "`date`"
