Bugfix/update docker php limits

[josvandervelde]

Updated the php settings to similar values as production.

The main time-drain was garbage collection. On production, /usr/lib/php/sessionclean is ran from crontab but.. it does not clean the code igniter sessions! Those sessions are only cleaned after a reboot:

[user]@openml2:~$ find /tmp -name "ci_session*" -type f -printf '%T+ %p\n' | sort | head -n 5 2>/dev/null
2025-04-14+13:01:16.5844657760 /tmp/ci_sessionib0csl6lo5l776dd19ee0vcbv41jff9t

[user]@openml2:~$ uptime
 up 97 days

I did not fix this on current production. It is now fixed for the new deployment, as far as I can see. I tested it by setting session.gc_maxlifetime=10 (seconds) and using openml-services (docker compose).

It would be great if anyone with some knowledge of PHP and Code Igniter garbage collection / session handling could take a look at this!

Hi @janvanrijn @joaquinvanschoren , it would be great if you could review this! These settings should be production-ready.

Looks good. This is only for docker, right? It doesn't affect the currently running production server?

[joaquinvanschoren]

Thanks! This looks fine as far as I can tell. Just left one note to make sure we can merge or not.

[joaquinvanschoren]

Is this still a TODO or do you think we can merge it?
