Infinitely trying to start a new server when compiled.

[Kayull]

Bit of a strange issue that I hope someone can shed some light on.

I have been trying to get the base script to work on various Macs, both Apple Silicon and Intel, and the base script works but only when run using python3 test.py.

Once I compile it then it tries to infinitely start a new server for some reason. I have compiled using Pyinstaller and cx_freeze, all the same issue.

The error I get is below:

...Infinitely does this...

The only way I have managed to get a compiled version to work is by using subprocess with the command lines like python3 -m pyftpdlib -w

I have compiled on both macOS Sonoma and Ventura.
Compiled using Python versions 3.9.6 and 3.12.1

Any suggestions are appreciated to try and figure out why this is happening.
