Howdy,

I could really use some pointers to troubleshoot excessive CPU usage by mysqld on a Dual 1.33 G4 XServe with 2GB RAM.

Version: MySQL 5.0.45
Mac OS X 10.4.10

Activity Monitor shows mysqld consistently at 80-130% CPU usage. Simultaneously I have Navicat's Server Monitor up. There are no mysql queries or connections coming through, other than my monitoring connections.

Below are the MySQL Variables and Status Lists. I would greatly appreciate any tips or pointer to improve performance in MySQL. Thank you!
