I installed the Analytics component. It was making so many queries to the database in a very short time, that it tripped the server's security rule and caused a temporary lockout. The server was interpreting the rapid sequential queries as a brute force attack. I had to uninstall the component in order to "unlock" the server. Why the multiple queries? It was happening when I was working in the site Administrator doing some miscellaneous site content updates.

The server is a dedicated VPS. I am using the most current version of Joomla 3.4, with PHP 5.4.

Please advise.
