Server stops responding every 10 minutes after php5-fcgid.conf configuration, why?

view story

http://serverfault.com – I have PHP5-CGI installed, Apache, and MYSQL installed. Prior to adding these settings, PHP5-CGI would endlessly have >15 processes, each eating up 5 mb of ram. So I added these settings to /etc/apache2/conf.d/php5-fcgid.conf and the PHP5-cgi processes were limited. However, now, everytime I open let's say 20 threads/pages in 4 or 5 minutes, the server stops running properly, things freeze and pages stop loading, until 2 or 3 minutes pass by, then it's lightening bolt fast again.
