I have three separate boxes running Apache 2.4, all with the same config and modules. On CentOS 7, Apache 2.4, PHP 5.6.
Two issues that could possibly be related. On one hand, I have not forced a restart, yet it would appear that apache restarted itself based on error_log being purged and having the below.
Second issue are the actual errors or warnings displayed. I can't figure out how to resolve them and if they could be the reason that Apache restarts itself in the first place, or be creating other issues elsewhere.

I'm making a symfony 3.4 application as REST service (so I have installed the usual JMS Serializer, FoSRest and lexik/jwt-authentication-bundle) and testing it on XAMPP (Windows 10).
When i make XHR requests through my frontend application using app_dev.php as endpoint it (very) often happens that Apache crashes when making 2+ requests at the same time.
Reading here and there it looks like that this issue is often caused by an attempt to write on the session file since symfony default session handler is session.handler.native_file.
So i first tried to put null (which, according to the documentation, uses native PHP session handler), this made the crashes happen less often but didn't fix the issue completely
Then i tried using Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler which made the crashes happen even less than before, but there's still the occasional crash
Now that i'm using a database as session handler though i'm noticing that no session is being written on the database when i make XHR requests (While it does if i open a normal web page served by the application), which shouldn't surprise me since I set my security.yml such that the REST routes must be stateless, and yet toying with the handler_id configuration influences how often my apache crashes
The same thing doesn't happen if I open multiple web pages served by the same application, nor it happens if I use the production endpoint (app.php).
Is there any way to fix this completely?
EDIT:
As requested
Can you add the apache error logs and php error logs?
It just repeats like this for each time it restarted. I have noticed this line: AH00428: Parent: child process 29076 exited with status 3221226356 -- Restarting. which might be interesting investigating upon

When you say apache crash means that you have to start apache again,
or you just get an error? Which error do you get?
I Just get the usual application crashed window saying "Apache has stopped working", if i click "Close the application" it restarts by itself and the request that caused the crash simply fails with no status code or error message (which is expected since the connection with the server stopped). As you can see there's no specific error in the logs except for that status code
How you have setup apache and php mod_apache, php-fpm? Which apache
server limits do you have, how many php workers?
I'm not sure how to answer this question, i'm using stock apache and php from the XAMPP package with no edits to the configuration. I can tell you php is loaded as apache handler, so no CGI or FastCGI. Anyways on simple pages or using production mode in Symfony it works fine
NEWS:
I have discovered that since i was doing CORS requests it was creating a session file for each request, i fixed that and it slightly improved my issue, but it's still there
I have tried using redis as session handler for PHP but it actually made things worse
I have made a simple test where i called the same page (which uses session) 1000 times, it works fine as long as i put session_write_close(); at the end, otherwise it crashes
As stated in my last comment, I tried using FastCGI and it fixed the issue.
https://blog.tiger-workshop.com/fix-various-apache-crashes-on-windows/
On this page there are 2 suggestions for the error i was receiving AH00428: Parent: child process 29076 exited with status 3221226356 -- Restarting. One fix is to add the following lines to httpd.conf
<IfModule mpm_winnt_module>
ThreadStackSize 8388608
</IfModule>
But it didn't work. The second fix is related to a bug that happens in windows when using PHP as Apache Handler https://github.com/vlucas/phpdotenv/issues/76 so i switched to FastCGI as suggested.
These instructions are more specific to XAMPP than the ones posted in the link above. You need to edit the file xampp\apache\conf\extra\httpd-xampp.conf
Comment the following lines

This is my first time setting up a site on AWS, and any help would be greatly appreciated!
Make sure whether Apache is running or not by issuing the below command:
ps ax | grep httpd | grep -v grep
or try to visit your index.html page.
Also, just for your reference, webmin was dropped by Ubuntu https://help.ubuntu.com/community/WebMin
I have a problem start apache from webmin, it works but webmin not registre it's running. And the log shows this failed.
In running procsses it work, and the testpages running on the server.

Renaming site configuration files in /etc/apache2/sites-available/* into *.conf helped.
Example, when enabling site dummy.com, configuration file must be named dummy.com.conf.
Another solution is to change this line in /etc/apache2/apache2.conf from:
IncludeOptional sites-enabled/*.conf
to:
IncludeOptional sites-enabled/*
