MySQL pegging CPU after the leap second adjustment.
So I find that my MySQL database is running high on CPU all of a sudden. I optimize the tables etc and no difference. I hunt around the internet to find that there seems to be a problem with this years leap second adjustment which sends MySQL into orbit.
The solution reset the date
date -s "`date`"
and it dropped back to normal.
