Probably caused by the Leap Second! /2012/07/july-1-2012-tomcat-problems-high-cpuload-probably-caused-by-the-leap-second/ /2012/07/july-1-2012-tomcat-problems-high-cpuload-probably-caused-by-the-leap-second/#comments Sun, 01 Jul 2012 12:43:10 +0000 http://linux.uits.uconn.edu/mas02041/?p=194 (Update posted, see below)

As posted in multiple places around the web:

Debian

/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"`

Update:

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:

https://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=6b43ae8a619d17c4935c3320d2ef9e92bdeed05d

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

date -s "`date`"

Gosling discusses his feelings on Oracle, Sun, IBM, NoSQL, and lots more.

Although even Gosling doesn’t know where Oracle is going to take Java, there is plenty in this interview to add to the drama.
