My Amazon EC2 micro instance has 100% CPU usage very often. I only have a wordpress installation on it. I'm still in production mode, so no users but I get 100% CPU usage.
Does someone know how to reduce it? I get Amazon Email notifications every hour because of that that lasts over a period of over 300 seconds.
I already moved my database to RDS but didn't solve that problem. It just made it a bit better. Before moving to RDS with my database my Website always totally crashed when loading just one webpage.
My mysqld.log gives a errno 12 error that's why I also did innodb_buffer_pool_size=256M in my.cnf but didn't bring anything.
Would be thankful for every tip.
