How to revert an update?

After December 23rd I am getting a random huge server load. About 80. Which disappears randomly after switching users off and on / restarting the server / restarting PHP-FPM. Especially after adding new users on CWP admin load spikes hardly in 1-6 hours. Also, about 5 days ago started - I can't install any SSL for a new or old domain. I am a CWPpro user. The question is - how can I revert to an older working version of CWP and prevent future updates?

The last update 0.9.8.1190 only had PHP updates in it.


Could you please advise of the following:

What 'errors' and/or 'messages' are being displayed in the logs?

On the main panel, what are you Top 5 processes?

What distro are you are you running CWP on?

VPS or Dedicated?

System Specs?

I did not find any useful info in the logs. I run 8 clone sites on the same script on 8 different users. Controlling CWP by admin login.

So, there is no useful info in domlogs. PHP slow log starts to write by all domains, as then the server becomes very slow, it is normal that PHP will execute very slow.

Only found some interesting lines in some log files (do not remember the names):

Too many connections in /usr/local/cwpsrv/htdocs/resources/admin/include/functions.php on line 0

Undefined index: start in /usr/local/cwpsrv/htdocs/resources/admin/addons/ajax/ajax_list_accounts.php on line 0

My main Top 5 processes usually are php-fpm executions of my sites.
The CPU load by them is up to 50%, sometimes spikes to 100%.
But this is the same in both cases, the server is loaded by 2 or 40-80.

After recent tests, I found 2-3 of 8 of my sites causing high load. Suspending these user accounts drops the load to 5-10 or even 2. Unsuspending them after night - load can go low to 2, or spike to very high.
There is no huge traffic on those 3 sites and there is no DDOS attack - tested by enabling "under attack mode" on Cloudflare.

I do not have an idea where can be a problem as all my 8 sites are clones.

So after playing with accounts suspensions, restarts, etc, in a couple of days, I can get a stable 2-5 server load.

Until the next user account is created and added new domain - the load spikes and if I delete that new account quickly - the load drops to previous levels.
If I do not delete the new account - I should do a long play as mentioned above.

When I manage to get a low load, it keeps for 5-7 days (load 2-3), then spikes to ~6 and runs stable on that load.
Until new account + domain are added.

I am running the latest CWP7pro on CentOS Linux release 7.9.2009 (Core) 3.10.0-1160.119.1.el7.x86_64

VPS 8 Core (2200 MHz), 30 GB Ram, 800 Gb SSD.

Regarding installing SSL I found Cloudflare didn't let it do, as by default setting it has "Always use HTTPs" enabled and redirects newly added domains to the https version.
It is strange, as 5-7 days ago new SSLs on CWP worked just fine with newly added domains on Cloudflare.

UPDATE:

These 3 problematic accounts were created in 2020-2021.
The rest accounts were created in 2023+.

Any of them can become problematic randomly by playing a suspend - unsuspend account game.

Are they all using the same package definitions (same limits)?
All using the same php-fpm version?
Can you switch to nginx for better performance, or is there something tying you to Apache?

Yes, the same limits and the same php-fpm for all users.
Apache is handling my needs very well, one of other my sites has traffic 3x more than these of my 3 problematic users together - and the server load now is 1.

Where are located all possible user config files? I need to compare these 3 problematic users with others.

Hello

Please run the following script and let me know how it goes

sh /scripts/phpfpm_rebuild_user_conf

It is also important that you check that the hostname has a valid ssl

I look forward to your response to help you resolve this situation

Also look at the PHP scripts, and change any references from '127.0.0.1' to 'localhost'
