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.
