[BlueOnyx:21520] Re: systemd php-fpm-7.0.service dies, won't restart

[Michael Stauber]

Hi Chris,

> I wonder if anyone else has had trouble with PHP-FPM on BlueOnyx5209R

Yeah, I have seen this before. The good news: It's fixed in SVN. The bad
news: Release of that update is on hold until all the IPv6 related code
changes pass muster.

Here are the two clues that indicate what was happening.

> # systemctl status php-fpm-7.0.service

Among other things it said this:

>    Active: failed (Result: start-limit) since Mon 2017-11-13 14:41:04

"start-limit" is a bit more clarified in the log excerpt further below:

> Nov 13 14:41:32 web40 systemd[1]: start request repeated too quickly for
> php-fpm-7.0.service

If Systemd gets hammered with requests to restart a service, it
eventually pulls the rug under that service, not letting you do anything
with it. I don't even recall what the exact timeout for this behavior
is, but it's unreasonably long.

> So we reboot.  And that clears whatever the issue is.

Indeed. A reboot clears this and also some other Systemd related
oddities like the occasional "policytoolkit violation" that happens when
you try to start certain services manually w/o using their Systemd Unit
files.

The fix in SVN takes care of these repeated service restarts during
certain transactions such as CMU-Imports or cases where a lot of Vsite
related changes happen.
