Running Django in Python 3.7.9. I am using channels so daphne is used but even when I using gunicorn the same results are obtained.
The error below is appearing randomly.
ERROR 2021-07-12 11:55:07,478 HTTP GET /static/customer/assets/js/jquery.min.js 500 [0.71, 127.0.0.1:55466]
ERROR 2021-07-12 11:55:07,479 Exception inside application: Single thread executor already being used, would deadlock
Traceback (most recent call last):

"Single thread executor already being used, would deadlock"
RuntimeError: Single thread executor already being used, would deadlock
I don't think this error has much to do with deadlock, but at times they are appearing together.

How can I resolve this?
I resolved this error by downgrading asgiref:
requirements.txt
asgiref==3.3.2
I solved this specific issues (occurred during fetch of static files) by running python manage.py collectstatic command. I assume, this way static files are not served by the same process. At least it solves my error.
