[magostinelli]

Describe the bug

After some time while service running fine, it stopped working, some timeout errors are inside nginx logs.

If you restart the php8.1-fpm.service it works again, but after some other time it freezes again.

Context

• Hardware: VPS bought online
• YunoHost version: 11.2.4
• I have access to my server: Through SSH and through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: 27.0.2~ynh1

Steps to reproduce

Start the service and wait until it freeze.

Expected behavior

Nextcloud running without problems.

I updated to last version (released after this issue), now I saw that php fpm is upgraded to 8.2, but I have the same error.

Not sure #615 will fix the issue but you can test with

sudo yunohost app upgrade nextcloud -u https://github.com/YunoHost-Apps/nextcloud_ynh/tree/testing

I've also faced timeout that I fixed with a higher memory footprint (100mb) in php-fpm configuration (control panel in the webadmin).

[magostinelli]

In my /etc/php/8.2/fpm/pool.d/nextcloud.conf i have:
php_admin_value[memory_limit] = 512M
php_value[opcache.memory_consumption]=128

The problem is still here.
