[debian-mysql] Bug#679723: mysqld: started using loads of CPU when leapsecond passed

[Julian Gilbey]

Package: mysql-server-core-5.5
Version: 5.5.24+dfsg-4

My mysqld recently started using loads of CPU, on two different
computers.  There was no obvious reason, and restarting the daemon did
not appear to help.  Finding a thread about mythtv suggested a
possible reason: the leap second which occurred at 23:59:60 GMT on 30
June 2012 (about 3 hours ago now).  Rebooting the computer seems to
have sorted the problem.

Obviously, this is going to be hard to reproduce and test - either it
will have happened to lots of people or not, and it probably won't be
reproducible until the next leap second occurs :-(

I'm running kernel 3.2.0-2-amd64 (linux-image 3.2.20-1) and running
ntpd.
