The PHP OPcache module is not configured correctly

"The PHP OPcache module is not configured correctly. See the documentation ↗ for more information.
The OPcache internal string buffer is almost full. To ensure that repeated strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP configuration with a value greater than 16."

opcache.interned_strings_buffer The default is 16, could you set it to 32?

Nextcloud Version: 25.0.3

This error is also in 25.0.4 version:

I tried to add 'opcache.interned_strings_buffer' => '32', in Nextcloud config.php but doesn't work

I don't know if it's the best way, but I solved it like this:

Create a file (opcache-recommed.ini) somewhere place and mount it, just change the size and restart the docker.

Volumes:
 - ./opcache-recommed.ini:/usr/local/etc/php/conf.d/opcache-recommended.ini

File Contents "opcache-recommeded.ini"

opcache.enable=1
opcache.interned_strings_buffer=32
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=60

Thanks @talesam !!

It seems this is already fixed in f8169f6. Just wait for the new release.

the problem still exists :latest. Is there any new information here?

@R7JANV1 I thought your issue was with the general opcache memory consumption ( #1965 ). Or are you getting a warning about string buffers, specifically? What warning(s) are you seeing?

I get the following error message:
The OPcache buffer is almost full. To ensure that all scripts can be kept in the cache, it is recommended to apply opcache.memory_consumption in your PHP configuration with a value higher than 128.

I posted above how to solve this

The issue still exists. IMHO this patch from nextcloud/all-in-one should be applied here as well: nextcloud/all-in-one#2762.

[rubo77]

still exists in NC 29.0.1

the workaround from #1926 (comment) still works

This is mostly being discussed in #2184 and associated PR #2185 at the moment. And we're also working on some upstream docs improvements.

So to avoid spreading the discussions around, let's consolidate there.
