I found mysqld (5.5.24) running at 159% CPU on a Ubuntu 11.04 (64-bit) box this morning. ntpd had drifted in the leap second between 1am and 2am (GMT) this morning (NTP drift info is one thing I graph with MRTG). [EDIT] Ah, covered elsewhere. Fixed by manually setting the date on the box; stopping/restarting mysqld or ntpd doesn't make any difference.
