uWSGI "SIGNAL QUEUE IS FULL" errors

I have a Django application running with uWSGI.
Sometimes, when restarting the uWSGI service, I get a bunch of *** SIGNAL QUEUE IS FULL: buffer size 212992 bytes (you can tune it with --signal-bufsize) *** errors.
When that happens, I'm unable to access the Django app. Restarting uWSGI again usually works.
Any ideas what happening here?
On startup of my application, I have a bunch of crons and timers that are initialized, like:
#uwsgidecorators.timer(30)
def send_queued_mail(*args, **kwargs):
...
The full output of the wsgi process is below:

It seems like issue may have arisen from duplicate timers. The solution is to import the timers before the loading of my WSGI app. My uwsgi ini file now looks like:
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /opt/%n
# Django's wsgi file
module = MY_APP.wsgi
import = MY_APP.processes.production
...
where MY_APP.processes.production contains all of my .cron and .timer declarations.
This was suggested to me in https://github.com/unbit/uwsgi/issues/2123 and is also found in the first example from the documentation: https://uwsgi-docs.readthedocs.io/en/latest/PythonDecorators.html.

uWSGI runs Python 2 with Plugin Python36 -> doesn't find Django in Venv

I'm trying to setup a simple Django project with Nginx, uWSGI on my Centos7-Server with this Tutorial:
How to Serve Django Applications with uWSGI and Nginx on CentOS 7
But I've tried to change this project into running Django 2 with Python 3.6
Everything worked pretty well, till creating firstsite.ini file.
1 [uwsgi]
2 project = firstsite
3 username = user
4 base = /home/%(username)
5 plugins-dir = /usr/lib64/uwsgi/
6 plugin = python36
7 virtualenv = %(base)/Env/%(project)
8 chdir = %(base)/%(project)
9 home = %(base)/Env/%(project)
10 module = %(project).wsgi:application
11
12 master = true
13 processes = 5
14
15 uid = %(username)
16 socket = /run/uwsgi/%(project).sock
17 chown-socket = %(username):nginx
18 chmod-socket = 660
19 vacuum = true
There I got stuck into. While setting up and trying to reach the Django Site I got an Internal Server Error. After checking error-log files and messages, I've implemented logto into my .ini file::
21 #Error Logs
22 logto = %(base)/%(project)/error.log
after checking this file it tells me this Error-Message::

If I manually try to get this django project runing with the same Env, there is no problem. So I thought that it could be because of the fact that uwsgi is running Python 2.7.5 instead of Python 3.6.
I also checked the plugin python with uwsgi --plugin python36 -s:0

So it looks to me, that I've created my 36-plugin the right way.
Would be really grateful if someone could help me out.
this is where the real problem is it can't find django
are you sure that django is installed in that environment you mentioned?
i mean "Env"
Traceback (most recent call last):
File "./firstsite/wsgi.py", line 12, in <module>
from django.core.wsgi import get_wsgi_application
ImportError: No module named django.core.wsgi
in that link you mentioned i couldn't find
virtualenv = %(base)/Env/%(project)
try changing it to
virtualenv = %(base)/Env
if that didnt solve your problem please specify django, python versions you are using plus your project structure

No module named 'django' uWSGI

in a nutshell I am getting the following error message from uWSGI when I try to test my installation against the examples found here:

So obviously it found my wsgi.py file, but not Django. I'm not sure if I screwed up installing uWSGI system wide, my virtualenv folder layout, or whatever. I had wanted to deploy my app soon, but this takes precedence since I want to use nginx and uWSGI. My directory structure:
~Env---
projectenv proj0
bin proj0
include __init__.py
libs __pycache__
. settings.py
urls.py
views.py
wsgi.py
Any help at this point would be great. Thanks.
It doesn't look like it's using a Python interpreter that has Django installed, so it's probably not seeing your virtualenv.
Did you take the appropriate step to add your virtualenv to uwsgi options?

uwsgi error bind(): Permission denied [core/socket.c line 769]

Setting up django to use uwsgi I can run it using the command uwsgi --ini kb_uwsgi.ini --http :8000 outside the virtualenv however trying to run the emperor command sudo uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data brings an error:

Here's the uwsgi file
# kb_uwsgi.ini file
[uwsgi]
http = :80
# Django-related settings
# the base directory (full path)
chdir = /home/ubuntu/webapps/kenyabuzz
# Django's wsgi file
module = kb.wsgi
# the virtualenv (full path)
home = /home/ubuntu/webapps/djangoenv
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 10
# the socket (use the full path to be safe
socket = /tmp/kb.sock
# ... with appropriate permissions - may be needed
chmod-socket = 664
# clear environment on exit
#vacuum = true
In the uwsgi file http port 80 is configured. By default, normal users are not allowed to bind to this port. That is why you are getting bind(): Permission denied. You can either give permission to the www-data user to use that port or use a different port.

SyntaxError when quickstart for Python3/uWSGI

I wasted many time but couldn't find a solution. Ask for help.
I use ubuntu server 14.04, setup uwsgi by:
pip3 install uwsgi
Then I create the test.py:
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return [b"Hello World"]
After I run:
uwsgi --http :8001 --wsgi-file test.py
It shows:

Why there is a syntax error for python3?
P.S sorry for my English :P
