Java leapsec issue causes high CPU

Seems like a bug is going around caused by leapsec in Java that causes high CPU. There is a simple fix for the issue.

For CentOS / RHEL 5 & 6

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

Wait for the CPU to go down and then restart ntpd

/etc/init.d/ntpd start

After doing this, see if the cpu usage falls down using top or your tool of choice. If not, restart of the ntpd service will do the trick.

Simple fix for a 1 second big headache !!!
