We have detected that your account executing a slow MySQL queries.

            Username: ~~~~~~

            Database: ~~~~~~~
            MySQL User: ~~~~~~~~~
            MySQL Query: show table status like \\\'cdb_%\\\'
            
            Slow MySQL queries are not allowed, because you share server resources with thousands of other users and your long lasting MySQL queries are slowering the server and other users are having MySQL performance and connectivity problems. Please optimize your MySQL queries as soon as possible.
            Here are some good articles how to optimize MySQL queries: http://www.google.com/search?q=optimize+mysql+queries
            
            Good tips how you can optimize your scripts and make our servers run faster:
            - disable all parts of your website that allows anonymous posting, such as open forums, guestbooks. These days automated software fills all open areas of web with junk and content spam and increasing your database size.
            - disable visitors monitoring and tracking (each move of your visitor makes database query)
            - disable all unused modules
            - disable internal stats for your website - use http://www.google.com/analytics/ for example
            
            We thank you for understanding,
