SOLVED cPanel php-fpm not restarting

[rob_gc_12]

When upgrading from 70.0.26 to 70.0.31 I had no issues. But when provisioning a new server at 70.0.31 I am getting the below problem.

## The issue
When I create a new website on a subdomain it works for a few minutes then shows the error:
```
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
```

If I tail the `apache2/error_log` and refresh the web page I get this:
```
[Wed May 02 15:29:12.931381 2018] [proxy:error] [pid 23528:tid 140003464619776] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /opt/cpanel/ea-php70/root/usr/var/run/php-fpm/01ec0cf803682d3d54723265378c356d92c1d647.sock (*) failed
[Wed May 02 15:29:12.931430 2018] [proxy_fcgi:error] [pid 23528:tid 140003464619776] [client 120.29.52.39:54765] AH01079: failed to make connection to backend: httpd-UDS
```

Now sometime after around 5-10 minutes it will start working again on its own. (maybe after it restarts php-fpm itself)

## The temporary solution
But if I go into the WHM `PHP-FPM service for Apache` and manually restart the php-fpm service, it will start working straight away.

Ok couldn't edit the above because your system says it's spam so ill add it here:

After the WordPress website is created there is a delay of 2 minutes before the .htaccess file is created (inside the public_html). As soon as these are created the website dies with the '503' error.

Even if I try and create it before the apache does it just appends the below and then dies:
```
# php -- BEGIN cPanel-generated handler, do not edit
# NOTE this account's php is controlled via FPM and the vhost, this is a place holder.
# Do not edit. This next line is to support the cPanel php wrapper (php_cli).
# AddType application/x-httpd-ea-php70 .php .phtml
# php -- END cPanel-generated handler, do not edit
```

If I manually restart php-fpm after the website dies it works again, or as said before it will start working itself again after 5-10 minutes (I assume when cPanel restarts php-fpm itself).

As I don't have a clear time when apache will do this I can't confidently restart php-fpm. So the website always have a downtime when provisioned.

Seems the issue is happening on servers upgraded from earlier versions as well.

Hi @rob_gc_12

Thank you for reporting this, it looks like we received reports of this issue overnight as well leading to the internal case CPANEL-20179. The issue is marked as critical and our development will be working on resolving it as soon as possible. The only workaround right now is to restart PHP-FPM as you had done already.

I would like to know, once you restart PHP-FPM manually after adding an account do you continue to experience issues with it?

Thank you,

What's the status of this case?
This bug has quite some impact and since v70 has been pushed to release I am hoping for an urgent fix.
Thanks for the update

Hi @B.K.

The case remains unresolved at this time. I'll do my best to update here when it is resolved. We will also add updates in our changelogs when they're available. You can check them here: Change Logs - Change Logs - cPanel Documentation
