I'm a EC2 bitnami wordpress user. In the previous night my Apache server down because port 80 have been used by varnishd and I killed it and it solved. But in this morning, mysql got error on my site. the site got error of "Error establishing a database connection” and I can't log in to mysql with the error of "ERROR 1040 (08004): Too many connections" in my ssh panel. When I read usage by using top command the cpu usage for mysql.bin over 300%. What should I do now? Help me please. Thanks.
