I am having a big issue with my server since thursday evening. It started out of the blue and as far as I know nothing was changed when the issue started.
I am getting a massive CPU load caused by mysql.
In WHM --> Process manager I can see this:
/usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --log-error=/var/lib/mysql/host-ipxxxxx.xxxxxxxx.com.err --open-files-limit=102400 --pid-file=/var/lib/mysql/host-ipxxxxx.xxxxxxxx.com.pid
The load on the CPU is 150 - 300 which in turn makes the load on my server massive. It should be max 8 I think but my server has a load of 20 - 60 constantly making my websites slow as hell.
In "top c" I see the exact same thing, same process eating up all my cpu power.
I really have no clue what to do. I have been googling since friday morning trying to figure out what is causing this but I am simply stuck and I am close to giving up all together.
I read topics here where people say you need to check mysql for errors, so I did check the host-ipxxxxx.xxxxxxxx.com.err log but I am not sure if even indicates a problem. Here are the last 300 entries:
I also read you should check slow queries, but the logs people refer to for me do not exist and I am not sure what to do with it.
restarting mysql does not help
restarting the server does not help
killing that process does not help
I increased the open-files limit as some people suggested, which also did not help
........
I am very new to all this server administrating but I am eager to learn so if anyone is able to help me how to handle this issue I would very much appreciate it.

Version: '5.1.72-cll' socket: '/var/lib/mysql/mysql.sock' port: 3306 MySQL Community Server (GPLv2)I also read you should check slow queries, but the logs people refer to for me do not exist and I am not sure what to do with it.
restarting mysql does not help
restarting the server does not help
killing that process does not help
I increased the open-files limit as some people suggested, which also did not help
........
I am very new to all this server administrating but I am eager to learn so if anyone is able to help me how to handle this issue I would very much appreciate it.
