Error establishing database connection

Hello,

So this has happened on two of my sites just after using this plugin to replace texts in my posts. So I am certain it is because of Better Search & Replace.

While it is a handy tool, upon changing “oload.tv” to “openload.co” in my posts, my sites now randomly gives “error establishing connection” error. The wpconfig files is set up properly but what happens is that the CPU usage while editing posts/ using search goes way up which causes the database goes down momentarily.
