Hello fellow forum members, I hope everyone is doing well. Today, I'm facing an urgent issue with PHP-FPM on my server, and I'm seeking some advice and guidance from the knowledgeable community here at the forum. The problem I'm encountering is that PHP-FPM is exhibiting very high CPU usage, and at times, it shoots up to 100%, overloading the server. I'm currently running an Intel Core i5 13th Gen 13500 CPU with 64GB RAM, but even with this setup, the CPU load is becoming unmanageable due to PHP-FPM. Here's a bit more information about my setup: Operating System: CentOS Stream 8 x86_64(Py3.7.9) Web Server: Nginx PHP Version: PHP 8.1 aaPanel Version: 6.8.29 The high CPU usage is causing performance issues for the website hosted on the server, resulting in slower response times and increased page loading times. I'm worried about the impact on the user experience and overall server stability. I have already tried the following troubleshooting steps to address the issue: Checked for any errors or warning logs in the PHP-FPM and web server logs. Reviewed the PHP-FPM pool settings to ensure they are optimized for the server's resources. Monitored the server using utilities like 'top' and 'htop' to identify any specific processes consuming excessive CPU resources. Increased the number of PHP-FPM workers to handle incoming requests efficiently. However, despite these efforts, the CPU usage remains persistently high, and I haven't been able to pinpoint the exact cause of the problem. At this point, I'm kindly reaching out to the aaPanel community for any suggestions, insights, or potential solutions that could help me resolve this issue. If any of you have encountered a similar problem with PHP-FPM or if you have any expertise in optimizing PHP-FPM for better resource utilization, I would greatly appreciate your input. Here are some specific questions that come to mind: Are there any specific PHP-FPM configurations that work well for servers with an Intel Core i5 13th Gen 13500 CPU and 64GB RAM? Could there be any specific PHP scripts or applications causing the high CPU usage? How can I identify and address these potential culprits? Are there any tools or methodologies that I can use to further investigate the root cause of the issue? I look forward to your valuable suggestions and assistance. Thank you in advance for your support! Best regards,

Hello, has the website been hacked? Check whether the slow log of php is normal? izsurya

aaPanel_Kern it is not hacked, I'm using a clean install and a clean new site. Having 1000+ realtime traffic.

It is recommended that you check the php slow log and mysql slow log, if there is, please ask relevant personnel to optimize it izsurya

This is the same for me (also with nginx) It can't be an attack, it occures ONLY when I make import changes on my WordPress site (as changing theme, or updating templates). Maybe Divi and WP-Rocket are not the best friend ever (?)

Paulo I’m not using any caching plugin still facing the issues, I give up now, searching for alternative

aaPanel_Kern i can’t read the logs file because file size is more than 2mb

I'm not going to declare victory too quickly, but by switching from PHP8.1 to 8.2 I've seen a clear improvement (yet to be confirmed).

Use other ways to view log files, if the command tail or vi or vim izsurya

aaPanel_Kern This process consume all the server

Hello, it is recommended to check the slow log of php8.1 izsurya

Hello, when it is slow, I suggest you check whether the server load is normal? And provide screenshots
Check if there are any processes occupying the CPU
Also check the php slow log and php load information

run a maleware scan of your website(s), eg. https://sitecheck.sucuri.net/
run a maleware scan of your local computer which you are using for upload and administration
use official images for your operating system, eg from https://centos.org/download/
put your website(s) behind Cloudflare.com and check/filter your traffic... you will see how much traffic comes from bots... it was with mine websites about 90%
check if your VPS runs with an hoster, who overbooks much - maybe choose another hosting company. I have good experience with Hetzner, AWS, LeaseWeb, Hosteurope. It can be that you work on your website(s) always the same time, eg when coming home from work... if there is much more traffic and a high overbooking (at night or at weekends), all VPS slow down. You can also speak to the support of your hoster, if the host machine of your VPS is overloaded and to move your VPS to a new host machine
use software only from trusted sources (eg Wordpress.com)
if running Wordpress or similar, try to disable plugins for performance testing
