I use RaspberryPi 3 B+ as development base for easy backup before I change anything.

Now I have setup a new one with python 3.6.8 and i seem to be unable to get uWSGI running.

1. The FreeBSD OS is on a SSD


2. The installed Python3 is version 3.6.8

The working system Has Python 3.6.7 and the Freebsd is on a MicroSD

(www) [webapp@generic ~/www/netwhere]$ uname -mrs

FreeBSD 12.0-RELEASE arm64

(www) [webapp@generic ~/www/netwhere]$ python --version

Python 3.6.8

(www) [webapp@generic ~/www/netwhere]$ django-admin --version

2.2

(www) [webapp@generic ~/www/netwhere]$ uwsgi --version

2.0.18

I do the same test to see if uWSGI is running, but it fails with a segmentation fault.
The Process is still running in the background, but the test website on 192.168.0.129:8000 gives a "ERR_EMPTY_RESPONSE":

(www) [webapp@generic ~/www/netwhere]$ cat test.py 

def application(env, start_response):

    start_response('200 OK', [('Content-Type','text/html')])

    return [b"Hello World"] # python3

    #return ["Hello World"] # python2

(www) [webapp@generic ~/www/netwhere]$ uwsgi --http :8000 --wsgi-file test.py

Any recommendations what next steps I could do?

I have setup two fresh RPI3b+

1. FreeBSD12 on a mSD Card


2. FreeBSD12 on a SSD connected via USB (no mSD Card)

I can't replicate the issue I described in my Question on either.

Right now I don't know what caused it, I'll try to investigate and post an Update.
