    I am getting :
    Database connection error (2): Could not connect to MySQL.
    Times after time. So I need to restart MySql time after time.
    How to investigate which website is causing the problem?

    Hi,

    Please check /var/lib/mysql/hostname.com.err error logs to get more information about it.

    Thanks,

    Also enable mysql.slow log in my.cnf to catch those slow mysql queries from websites.

    Also try running mysqladmin processlist a random times to see - you can even create a php script to check every minute and to inform you of this occurring at the exact time.
