In the overview section of Nextcloud version 32.05 i get the following warning

PHP opcache

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 have tried to correct this by changing the value of the opcache.interned_strings_buffer in /etc/php/8.2/apache2/php.ini

; The OPcache shared memory storage size.
opcache.memory_consumption=128

; The amount of memory for interned strings in Mbytes.
opcache.interned_strings_buffer=64

Because I did not see any results, I also changed the value of the opcache.interned_strings_buffer in the etc/php/8.2/cli/php.ini file

I still get the warning.

I was wondering where I can change the value to solve this problem?

I have seen previous topics on this subject, and I have tried to find any answer there, but none of the topics is telling exactly which path to follow in order to change the correct file.

Further information about my Nextcloud setup is that i run it as a VM on Proxmox 8.X

In the overview, it stated that I am running Nextcloud Hub 25 Autumn (32.0.5)

It is a Turnkey VM that is running on Linux 6.1.0-42-amd64 x86_64 Operating System

Memory 4GB and Processor is 2

Nextcloud is behind a Reverse Proxy (Traefik version 3.6.4)

Let me know if there is more information needed

Hi, maybe it helps.

My configuration is:

ocache.memory_consumption=128

opcache.interned_strings_buffer=20

And please control that

opcache.enable=1

opcache.enable_cli=1

Thanks!!

I had already found the solution you offered. But still, many thanks to you.

I found out that, indeed, you have to enable the OPcache

The confusing thing is that you have multiple PHP ini files, and it is unclear which one you need to edit. In my case, I edit the apache2/php.ini file

Keep in mind, that PHP works much better when used as FPM and not as module in Apache.

What is FPM?

6

FPM = FastCGI Process Manager

The basic idea is to run php-fpm as service which also handles OPcache etc. and starts worker processes as needed and let Apache communicate with php-fpm using proxy_fcgi. The advantage is, that you separate the webserver from PHP and that multiple PHP processes can run in parallel.

Thanks for the explanation
