questions about php-fpm an load

[leonep]

hi,
i want to know more about php-fpm. I have my dedicated server wih cloudlinux and php-fpm on demand
maxchildren 5
timeout10
maxrequests 20

Recently i have more load specially on cpu. the server is around > 2.8 . in cloudlinux snapshots i have some accounts triggering limits.
Opening cloudlinux shapshots i have php-fpm process each consuming cpu , like this:

3666732	php-fpm: pool xxx php-fpm: pool xxx	16%	88
3666735	php-fpm: pool xxx	0%	55
3666738	php-fpm: pool xxx	0%	54
3666742	php-fpm: pool xxx	15%	88
3666744	php-fpm: pool xxx	5%	107
3666749	php-fpm: pool xxx	12%	104
3666754	php-fpm: pool xxx	13%	102
3666768	php-fpm: pool xxx	13%	101
3666771	php-fpm: pool xxx	10%	101
3666775	php-fpm: pool xxx	15%	101

the limit cpu in cloudlinux is 100%

this is only more traffic? the maximum number of master php-fpm process can be set ?any suggestion for tunung?
thanks for help

Hello,
You can try to check if this is a DDoS attack and not a problem with fpm/apache, also set up the apache configuration and switch from fpm to something else, for example, fcgi/lsapi.
