As stated in .. and other posts, the defaults of uWSGI not suitable for a productive environment. To give just one example, the workers run indefinitely and the memory leaks aggregate. - "Configuring uWSGI for Production: The defaults are all wrong" EuroPython 2019 [1] - "Configuring uWSGI for Production Deployment" [2] - "When Paul has tested some PR on his instance, we could clearly see a memory leak over a week: the memory never dropped to the initial value. Same for my instance using Docker."
