PHP OPcache module is not properly configured: OPcache interned strings buffer is nearly full

[meonkeys]

Since upgrading to 23, I'm seeing this at /settings/admin/overview:

• The PHP OPcache module is not properly configured:
  • The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP configuration with a value higher than 8.

I haven't changed any PHP settings, I'm just using the upstream nextcloud image with the tag 23. Looks like I have version 23.0.1.2 now.

This issue is also affecting my instance - docker container

Simple enough fix. Follow the instructions: edit your php.ini file and set opcache.interned_strings_buffer to a value higher than 8. I chose 16, restarted my php service, and everything's fine.

As the value is set in the Dockerfile and thus would be overwritten when pulling an updated image.
It would be best to change the lines https://github.com/nextcloud/docker/blob/master/Dockerfile-debian.template#L96 and https://github.com/nextcloud/docker/blob/master/Dockerfile-alpine.template#L82?

Same here. Agree.

Okay, created a PR #1702

To solve this until the PR #1702 is added:

docker exec -i -t next_your_domain_app_1 bash -l
sed -i "s/opcache.interned_strings_buffer=8/opcache.interned_strings_buffer=16/g" /usr/local/etc/php/conf.d/opcache-recommended.ini |grep opcache.interned_strings_buffer /usr/local/etc/php/conf.d/opcache-recommended.ini
