Please find the attached python file where the issue is seen.
The cli to create an executable was:
$pyinstaller run_server_min.spec

Here are the contents of the file (this doesn't support multiple file uploads):
================
# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['run_server_min.py'],
             pathex=['<PUT ABSOLUTE PATH OF ABOVE FILE HERE>'],

             hookspath=['pyhooks'],

             cipher=block_cipher)

          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],

=========

$ pyinstaller run_server_min.spec
69 INFO: PyInstaller: 3.5.dev0+cb8d10af6

...

When your run ./dist/run_server_min that is generated, it'll spawn the process multiple times. The issue goes away when you add freeze_support on the top.
