Unfortunately I still need to use mysql...
ps axu
mysql 24466 33.7 0.5 28756 5808 pts/4 S 13:42 0:26 /usr/libexec/mysqld --defaults-file=/etc/my.cnf --basedir=/usr --datadir=/v...
The 33.7 is the %CPU.
Yet 'top' shows mysql using 0 cpu and 'show processlist' doesn't show any processes other than 'show processlist.' Something seems to be loading my server (load average 2-5), but I can't really figure out what.
