We get the same thing on FreeBSD machines quite often, and it's not
related to the actual work being done; MySQL can sit idle but use up all
CPU. It happens after a few days/weeks of uptime.
Switching to Linux fixed it ;)
The difference with what Dicky describes is that for us the MySQL
servers still works; it just looks like there's a rogue thread running
around doing nothing.
