[BlueOnyx:21519] systemd php-fpm-7.0.service dies, won't restart

[Chris Gebhardt - VIRTBIZ Internet]

Hi all,
I wonder if anyone else has had trouble with PHP-FPM on BlueOnyx5209R / 
CentOS 7 dying and then not being able to restart?   I have run into 
this again today with one of our shared hosting systems.  The good news 
is that sites not on the particular PHP runs fine.  The bad news is that 
the server has to be rebooted to get the affected PHP back up and 
running again.

Here's a bit of the way this shakes out.  Service fails, so we check the 
httpd error log and get this:
[Mon Nov 13 14:39:51.512076 2017] [proxy:error] [pid 6790] 
(111)Connection refused: AH00957: FCGI: attempt to connect to 
127.0.0.1:9040 (*) failed
[Mon Nov 13 14:39:51.512150 2017] [proxy_fcgi:error] [pid 6790] [client 
217.182.132.187:34724] AH01079: failed to make connection to backend: 
127.0.0.1

The next step is to check the service status:
# systemctl status php-fpm-7.0.service
* php-fpm-7.0.service - The PHP-7.0 FastCGI Process Manager
    Loaded: loaded (/usr/lib/systemd/system/php-fpm-7.0.service;

OK, clearly it's dead.   So we'll issue a restart:

# systemctl restart php-fpm-7.0.service
Job for php-fpm-7.0.service failed because the control process exited 
with error code. See "systemctl status php-fpm-7.0.service" and 
"journalctl -xe" for details.

No go.   Don't have a lot of time to screw around because the server 
should be in production in the middle of the day.   So we reboot.  And 
that clears whatever the issue is.

Just thought I'd report it.
