Mysql stops and my wordpress stops working
I am new to this server, apparently it is a mysql problem that stops when you consume too many resources, someone can help me.
I have a VPS with 500MB Ram digitalocean with Centos 6.5 x64
This is the configuration file of my mysql, the logs can see below. I hope someone can help, of course many thanks.
