cPanel vps high cpu and all Apache connection used..

[webstyler]

Hello

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
