Has anybody ever snapped gunicorn?

[Robert Park]

Right, so that was a $PYTHONPATH issue indeed which I've fixed by
setting this in a wrapper script:

export PYTHONPATH="$SNAP/usr/lib/python3/dist-packages:$SNAP/src"


But still gunicorn is not working. When I run it, I get this error:

$ sudo quantifiedself.server
[2016-10-09 16:30:13 -0700] [4365] [INFO] Starting gunicorn 19.4.5
[2016-10-09 16:30:13 -0700] [4365] [INFO] Listening at:
http://0.0.0.0:8080 (4365)
[2016-10-09 16:30:13 -0700] [4365] [INFO] Using worker: sync
fish: “sudo quantifiedself.server” terminated by signal SIGSYS (Bad system call)


All I can find in kern.log is this, but it doesn't mean much to me:

236:Oct  9 16:30:02 rouge kernel: [1793707.594342] audit: type=1400

Anybody have any ideas how to troubleshoot this?

Thanks.
