Hello I have a dedicated server with debian 6 and ispconfig3. For several days I have too many connected users and the server is unusable. The cpu is always at 100% and I have to stop apache to solve. Is there something to set max 500 connection to apache? for example mod_bw module for apache.
Use Apache's MaxClients Directive in the 'worker MPM' section of your Apache configuration file (/etc/apache2/apache2.conf), or switch to Nginx or litespeed.
