Summary of the issue you are facing:
I cannot get any response from the backend. There is connection to Apache, but no response from the application.
I found the following in the log file for PHP-FPM:
server reached pm.max_children setting (8), consider raising it
I have never had the need to tweak anything in here, and this service has been running for years. I raised it to 40 and tweaked the remaining settings to fit the 40 and restarted. It seemed to work. For two days. Then it returned.
server reached pm.max_children setting (40), consider raising it
Now I could just raise it, but I suspects there is a resource leak in Nextcloud. Could be in an app, but I do not know how to troubleshoot that.
Steps to replicate it (hint: details matter!):
N/A
Log entries
Nextcloud
Please provide the log entries from your Nextcloud log that are generated during the time of problem (via the Copy raw option from Administration settings->Logging screen or from your nextcloud.log located in your data directory). Feel free to use a pastebin/gist service if necessary.
I see only timeouts of the applications, as well as timeouts towards the richdocuments proxy endpoint.
Due to the errors in regard to Nextcloud office, I disabled both that and the CODE app. However I still noticed the same thing happening.
Web Browser
If the problem is related to the Web interface, open your browser inspector Console and Network tabs while refreshing (reloading) and reproducing the problem. Provide any relevant output/errors here that appear.
PASTE
Web server / Reverse Proxy
The output of your Apache/nginx/system log in /var/log/____:
Nothing other than successfull connections.
Configuration
Nextcloud
The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
