Cause of the Issue
------------------

The Apache service has reached its open file limit. 

How to Resolve
--------------

#. Log in to the server at the CLI as root, either via SSH or from the terminal
#. At the CLI, using a text editor, create a new file named ``/etc/systemd/system/httpd.service.d/limits.conf``. The
   following uses the Vim text editor:

   .. code-block::

      vim /etc/systemd/system/httpd.service.d/limits.conf

#. Add the following setting. This example sets the limit to 20000, however, this setting should be customized 
   based on server needs:

   .. code-block::

      [Service]
      LimitNOFILE=20000

#. Save the file and exit the text editor
#. Reload the daemon and restart Apache

   .. code-block::

      systemctl daemon-reload
      systemctl restart httpd
