Hello folks,
Sometimes you faced issue with the MySql queries like as you not able to run simple query even. It it is due to there should be a limit set on the server for your hosting account for maximum concurrent connections of mysql. You can kill the mysql processes from the PhpMyAdmin and starts new one.
Login to cPanel and go to PhpMyAdmin.
From here, you can view the current MySQL processes by selecting the Status tab at the home page of phpMyAdmin.
To kill a process, click the kill link to the left of the process ID number.
That's all, Enjoy .. :) ;) :)
