Apache 2.4 - multiple WSGI Virtual Hosts (different ports) hangs after few requests from one to another on Windows 10

Question

I'm trying to host two different apps on different Virtual Hosts with different ports on Windows 10. Problem is that apache completely hangs after few requests from one app to another.

Hosting them on one Virtual Host with different paths seems to solve the problem, and so does disabling requests.

Both apps are Python Flask web servers.

httpd.conf

Listen 80
Listen 3000

ServerName localhost

<VirtualHost *:80>
    WSGIScriptAlias / F:\path\to\server.wsgi

    <Directory F:\path\to>
        Require all granted
    </Directory>
</VirtualHost>

<VirtualHost *:3000>
    WSGIScriptAlias / F:\another\path\to\server.wsgi

    <Directory F:\another\path\to>
        Require all granted
    </Directory>
</VirtualHost>

AcceptFilter http none
AcceptFilter https none

Answer 1

Seems that i found the solution:

If you using C modules in your apps then add this line inside VirtualHost

   WSGIApplicationGroup %{GLOBAL}
