The settings that I posted are not for everyone to use. They were for the person who was having problems. Each person's system has to be tuned to their site.

The "too many connections" issue means that you need to increase your connection limit in mySQL. Your settings are too low for your site's traffic.

The "mySQL server has gone away" issue means that your timeouts are too short for the time that it is taking to convert your videos. You will need to increase your mySQL timeout.
