It's a server side issue our website and app are crashed and Optimize CentOS Apache Server

We are facing frequent server crashes on a CentOS-based Apache server with PHP-FPM setup. The issue seems to be caused by high CPU usage from PHP-FPM processes, especially under load on certain API endpoints.

PHP-FPM consuming 60–80% CPU per process.
Load average spiking up to 4.0+
Server frequently going down.
Log errors: client denied by server configuration: /home/facilitymate/public_html/api
Need to trace high-load PHP scripts and fix config/performance issues.

- We Need Someone Who Can:

Audit and optimize PHP-FPM + Apache settings.
Identify and fix poorly optimized PHP scripts or queries.
Implement slowlog for PHP-FPM and interpret the output.
Configure rate-limiting (Cloudflare or server-side).
Suggest long-term performance improvements.

- Required Skills:
Linux Server Administration (CentOS preferred)
Apache (MPM Event), PHP-FPM tuning
Familiarity with cPanel/WHM
MySQL performance debugging is a plus
Cloudflare Firewall & Rate Limiting setup
