First allow me to intoduced my self here
i have read this thread, same problem but different source of problem.
Prologue
We (me and my team/ campus) have a dedicated server placed in our place. we choose WHM as our tools to manage server, and have a little (almost zero) knowledge about how managing a server. Before we use WHM, we rent a hosting to host most of our website. but we concerned about our student data, and decided to build own server.
Part 1 (server spesification)
Total processors: 32Processor #1Vendor Genuine IntelNameIntel(R) Xeon(R) Silver 4110 CPU @ 2.10GHz Speed 2100.000 MHzCache 11264 KB
And Dedicated Connection 50 Mbps with Mikrotik OS as Router
PART 2 (base on this recommendation)
How many sites on the server?
Currently 44 Account in our account list. every account consist about 2-3 websites. majority of website we using wordpress.
Beside sites, we have a Open Journal System (OJS) 2 and 3 Installed on Server (one most most consistent traffic).
and of course Academic Information System. (AIS)
most (not all) AIS built with Code Igniter.
one REST API server built with Lumens.
What is the normal load averages?
on daily use, we just have a little problem with server load. only 1 month every semester we have high load problem because a lot of activity in initial semester such as student make a study contract, input student grade, prepare class data, sync with our government server about study data.
How much ram is on the server?
32 GB.
What version of PHP are you using?
Mixed
but a majority use 7.3 only a small portion using 5.6. but most of 5.6 App will be there (just for data show) but not for CRUD.
Do you have PHP opcache installed?
yes, we have PHP opchace Installed
What database version are you using?
in this early month we currently using remote MySQL (different server with local ip)
Server: xxx.xxx.xxx.xxx via TCP/IP
Server type: MySQL
Server connection: SSL is not being used Documentation
Server version: 5.7.29 - MySQL Community Server (GPL)
Protocol version: 10
Apache Global Conf

Max Children 25
Problem
Every time our server stuck/ crash (when a lot of Process wait to send Reply (a lots of W )), we must restart PHP-FPM server sometimes PHP-FPM and http server (apache) before we move out out DB. we restart mysql services too. this problem happen not very often. only when we start new semester. daily average just need not more than twice a day. on daily basis just Presence App and our website running. not many user (student and lecturer) accessed AIS.
Epilogue
this problem happen because we miss configuration our server or (and) our bandwidth is too small to handle the request? if bandwidth to small. why we can still access WHM (or another port beside 443 or 80) with no problem. we still can reset out server with WHM interface in port 2087.
Please help us.
thank you.
