Main Processes:Multiple php-fpm processes from the admin pool are consuming a significant amount of CPU (around 50% each).The MySQL process is also consistently active, with many queries in "Sleep" state.
 
check your logs and website code, is it normal for website to have opened connections few hours? is it some realtime-online project?
 
your scripts must report something to own logs,
also check apache/nginx logs
 
This how I identify issued.

1 : Check in Resource Limits, find users have some high Task, CPU, Mem, Disk IO
2 : Read logs size of all their website.
3 : Check some logs which have hight avg size, find weird spam request URI Path.

p.s. Resource Limits is propack feature.
 
I verify in the consumption that the php-fpm: pool admin is the one that has excessive consumption

you can see same on your first post, you need to check logs to find out what exaclty causes load.
also you can check mysql processlist to see requests.
 
This is error log.

Apparently you have problems reading the fastcgi, try to fix it with this command although it does fix most of the same error but it continues to persist. I don't know if this is adequate to solve it?

echo 'ProxyTimeout 1800' >> /etc/httpd/conf/extra/httpd-includes.conf
service httpd restart
