### Steps to reproduce
1. Upgrading to Nextcloud 21
2. Run ``php ./occ`` in Nextcloud root directory
3. ``./occ`` crashes
### Expected behaviour
Occ should work normally, for example printing available commands
### Actual behaviour
Occ crashes with the following error:
```
$ sudo -u http ./occ update
PHP Warning: Module “gd” is already loaded in Unknown on line 0
PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /usr/share/webapps/nextcloud/lib/private/AppFramework/Utility/SimpleContainer.php on line 133
```
To be more precise, this also happens running php cli against other files of Nextcloud, for example ``index.php`` or ``console.php``.
Surprisingly Nextcloud is running fine through php-fpm and web server. It was even able to perform the upgrade to v21 just fine.
Another user commented on the [ArchLinux bug tracker:](https://bugs.archlinux.org/task/69726#comment197002)
> If it could help, I added a trace in /usr/share/webapps/nextcloud/lib/private/AppFramework/Utility/SimpleContainer.php on line 133, and I get in an infinite loop the following messages:
>
> Could not resolve OC\User\Manager!
> Could not resolve OC\Security\CSRF\CsrfTokenManager!
>
> As if it was unable to locate its lib/private/ folder.
> If I set memory_limit to -1, it fill completely memory and hit OOMkiller.
> (tried with both php7 and php8, with nextcloud-21.0.0-7)
Possibly not only related to ArchLinux setups. An other user reported the exact issue [here](https://help.nextcloud.com/t/nextcloud-consuming-all-memory-and-swap-and-crashing-server/108532), which was triggered on a Ubuntu installation.
