This process has been using 65% of my site CPU and has lasted for about 10 minutes now (aren't processes only supposed to go for a couple seconds?)

It is obviously something with mysql. This makes sense because I have a lot of queries going, but something still seems a bit odd...

This could have something to do with my bad PDO connection that I mentioned in the previous question. Perhaps I am opening too many connections or something like that?

Here is the stats on it:

Owner: mysql
Priority: 0
CPU %: 61.1
Memory %: 0.4
Command:/usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/cvps54834319.myhost.com.err --pid-file=/var/lib/mysql/cvps54834319.myhost.com.pid

Thanks for any help on this. I have over 10GHZ on my server so this is very concerning to me.
