Nextcloud 21 - Only 384 MB PHP memory limit available


as my hosting provider currently only allows 384 PHP memory limit, I wanted to ask, how important it is to really run Nextcloud 21 with 512MB memory limit.

Thanks in advance.

Without having enough memory you might run into problems using some functions of Nextcloud. Base system requirements aren’t set out of the blue, furthermore the memory limit of 512MB already exists for several Nextcloud versions and isn’t related to v21 only. I would recommend to upgrade your subscription asap.
