The issue you are facing:
while checking the opcache, I noticed errors when running the command “sudo -u www-data php /var/www/nextcloud/occ setupchecks -vv”
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- sudo -u www-data php /var/www/nextcloud/occ setupchecks -vv
- and the error is displayed in red

Error Opcache
opcache PHP: The PHP OPcache module is not correctly configured. OPcache does not work as expected, opcache_get_status() returns false, please check the configuration.
The maximum number of OPcache keys is almost exceeded. To ensure that all scripts can be cached, it is recommended to set the "opcache.max_accelerated_files" variable in your PHP configuration file to a value greater than "10000".
The OPcache memory buffer is almost full. To ensure that all scripts can be cached, it is recommended to set the "opcache.memory_consumption" variable in your PHP configuration file to a value greater than "128".
The OPcache internal strings memory buffer is almost full. To ensure that repetitive strings can be cached, it is recommended to set the "opcache.interned_strings_buffer" variable in your PHP configuration file to a value greater than "8".
Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

I have the impression that the parameters are not taken applied by Nextcloud because I control the opcache parameters by executing:
cat /etc/php/8.2/apache2/php.ini | \
egrep "^;* *opcache\.enable *=|^;* *opcache\.interned_strings_buffer *=\
|^;* *opcache\.max_accelerated_files *=|^;* *opcache\.memory_consumption *=\
|^;* *opcache\.save_comments *=|^;* *opcache\.revalidate_freq *=\
|^;* *opcache\.interned_strings_buffer*="
I have the following result:
opcache.enable=1
opcache.interned_strings_buffer=128
opcache.max_accelerated_files=100000
opcache.save_comments=1
the parameter “opcache.memory_consumption ,opcache.revalidate_freq” is missing.
I have no errors in the nextcloud interface , but only when I run “sudo -u www-data php /var/www/nextcloud/occ setupchecks -vv”
Do you think my configuration has errors?
Thanks for your help
