    VPS with 2 vCpu and 2GB RAM

    only 1 site onboard, with wordpress

    There are installed mod_security and CSF

    This machine have a high cpu usage, Apache have full connetion, there isn't slot free for new connection

    Under Process manager we have a tons of
    Nobody 0 0.0 0.2 /usr/local/apache/bin/httpd -k start -DSSL

    Under Apache Status we see a lot of
    17-0 19953 0/11/11 G 0.26 191 0 0.0 0.07 0.07 36.**.**.29 77.**.**.73 NULL


    We have set CSF block based on connection tracking and on mod_security trigger, but we are sure there is a lot of bad traffic..

    The apache configuration :

    Start Servers : 5
    Minimum Spare Servers : 5
    Maximum Spare Servers : 10
    Server Limit : 384
    Max Clients : 300
    Max Requests Per Child : 300
    Keep-Alive : On
    Keep-Alive Timeout : 25
    Max Keep-Alive Requests : 25
    Timeout : 300

    If we switch off Keep-alive server cpu load go 199 and more :/

    The same if we lower keep-alive timeout

    Any suggest for bring more traffic, lower cpu usage and discard bad connection ?

    Thanks for any suggest
