Long story short

unexpected processing during shutdown

Expected behaviour

I am writing a server code that connects clients though WebSockets. The server that I coded calls the close all Websockets connected (maintained in a set as the documentation recommends), and I expect the code calls the close() method of the websocket as many time as web sockets are connected.

Actual behaviour

Right now, there is only one close being called. After the first call, it is like the server continues executing the rest of the shutdown processing.

Steps to reproduce

Start the server with python server.py
Start two clients with with python client.py

Ctrl-C on the sever and you only see one print with the label closing websocket
