Wait your telling me a PHP Application not responding correctly is not a bug...
So what your deliberately leave the connection to apache2 open when it a handled error happens, even
though no error it closes the connection correctly?

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
Besides the fact that the problem clearly appears to be with the LB, this is too complicated to deal
with on a bug tracker. Too many variables. If you can eventually track down the problem to something
specifically with php-fpm (which has no knowledge of your LB because Apache is in between) then we
can work from there.

Description:
------------
This is a pain to replicate but spent 2 hours with AWS engineers (plural) working this one out.
Load Balancer to Apache2 to PHP7.2-FPM
Wordpress 5 - Database Connection error (Firewall / security group blocking access to Database)
PHP builds response and output and works correctly if you we used curl to the server curl with the
"host:" header we could see the full HTML response generated by Wordpress.
When going via a Load Balance on AWS (Application Load Balancer) the underlying apache connection to
the server was never closed so the load balancer just keep waiting for the connection to close
before time out.
Test script:
---------------
Wordpress 5
Expected result:
----------------
When Wordpress handle the DB connection error and produces a complete error output it should close
the connection to apache.
Actual result:
--------------
Seems to hang and leave the connection open meaning apache does not close it's connection
correctly
