There was some problem with resource consumption when you have enable APCU but it wasn’t enabled for the command line version (CLI) of php:

> [@\[SOLVED\] Occ command; PHP Fatal error, Allowed memory size of XXX bytes exhausted](https://help.nextcloud.com/t/solved-occ-command-php-fatal-error-allowed-memory-size-of-xxx-bytes-exhausted/108521/17):
>
> I had APCu activated in the nextcloud config.php. It seems I didn’t have apc.enable\_cli=1 in /etc/php/8.0/cli/conf.d/20-apcu.ini. After I added that line to the file occ worked and there was no segmentation error anymore.

Your php eating up RAM could be the same.
