Guys in my server i am facing high load as my site run many queries at a time. And so i enabled cache yesterday. so after that site performs faster .
Now suddenly i get message when accessing my site saying that "Couldn't make Connection".
So i entered in to root and i type " top"
And i see there is no mysql running http://prntscr.com/x6pjt , what can be the issue?
Is there any one experience in this can help me?
