Description

An unhandled Exception occurs on the ASGI server when one of the clients closes its connection due to erroneous socket connection handle.

System information

1. Kali Linux
2. 2023.3
3. Raspberry Pi 4

Actual Behavior

• After the client socket connection is closed, an unhandled Exception occurs on the ASGI server.
  • The Exception occurs on a Thread that handles execution _pubsub_data_reader() method from WebSocketBroker class.
  • It occurs when a publisher publishes a message to the Redis channel which has a closed socket connection in its pool.

Expected Behavior

• Once the connection is closed, it should be removed from the socket pool.
• When publishing messages to a channel, sockets should be checked if they are open.

Steps To Reproduce

1. Start the Redis server
2. Start the ASGI server
3. Start the React server
   • Open another client in a new tab (this creates a new connection).
   • Close the original tab (this closes a connection).
4. Start the Sniffer

Anything else?
