Fixes and workaround to avoid issues caused by Leap Second 2015

During last days we have encountered some servers with CPU spike at 100%.

In all case these servers was on VMWARE all of that with SLES and all of that with different services like Domino or IBM Connctions and on all of that different process takes the CPU .

After some times we have found the root cause, the Leap Second !

To fix the issue we have done the following :

/etc/init.d/ntp stop
date -s "`date`"
/etc/init.d/ntp start

Here you have the Suse technote that confirm if you have not an upgraded server you can have this issue.  See the technote for all detail about Sles version and kernel affected
