^^ from the apache error log of one of the sites on this server.

Reverse proxies unaffected, just PHP applications - namely in this case WordPress.

Happens after a while, corrected only by restarting PHP-FPM

Going to any webpage served during this time shows:

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Whats does that mean compared to Rocky 9.4?

3

LXC container, instead of bare metal or normal VM. Shouldn’t be the contributing factor here as run many virtual min servers this way but mentioning it incase.

4

fpm is a service, does lxc run services differently?

5

not that im aware of.

6

have just noticed have a pending fpm package update. will update and see if it does it again…

7

try this command
systemctl status php80-php-fpm

8

root@vhost1:~# systemctl status php80-php-fpm

Unit php80-php-fpm.service could not be found.

9

so it has not restarted

10

Strange. You can use the restart icon to restart from your last screenshot.

12

13

I am having this same issue at this moment

14

does the /run/php-fpm/ directory exist? As my Rocky9 doesn’t have that directory.

This is my settings it seems a bit different

According to the settings you sent there, do you have any issues?

I am also using Rockylinux 9. but this is a PHP 7.4

16

I encountered the same problem.

17

So you can see /run/php-fpm/ in the file manager. All people reporting the error are using the directory in the config.
How are you installing php versions, are you following the docs.

18

No I have not done this configuration.

Would there be something I would to do first before doing this when I have already multiple PHP versions?

Installing additional PHP versions
On RHEL, Alma, Rocky, Oracle, CentOS Stream and Fedora Linux
Install Remi repository
. /etc/os-release && repo_dir=$([ "$ID" = "fedora" ] && echo "fedora" || echo "enterprise") && dnf -y install "https://rpms.remirepo.net/$repo_dir/remi-release-$(rpm -E %$ID).rpm" && dnf clean all
Install PHP packages
dnf install php81-php-{cli,fpm,pdo,gd,mbstring,mysqlnd,opcache,curl,xml,zip}
Replace php81 with the desired PHP version, e.g., php83.
Check available PHP versions and extensions in the Remi Repository or use dnf search php.

This I did do

for php in $(scl list-collections 2>/dev/null | grep 'php' | sed 's/$/-php/') php; do for ext in curl intl; do sudo dnf -y install "${php}-${ext}"; done; done

This I did not do

It seems so far it is behaving after I ran that last command for the PHP extensions. Let us see if it happens on Monday. Thanks!
