[Bug] Ungraceful closing of EUD connection

[maxlandon]

I have observed several instances of the following exception being thrown in my OTS logs recently:

[2025-11-27 11:49:04,442] - eud_handler[1031] - client_controller - on_channel_close - 134 - ERROR - RabbitMQ channel closed for DOG, shut it down

  File "/usr/lib/python3.12/ssl.py", line 1291, in shutdown
    super().shutdown(how)
OSError: [Errno 9] Bad file descriptor

Note that it does not seem to have affected the functionality of the server or the clients.

Also seeing this, exact same error. I'm also having some issues with specific EUDs not seeing any traffic on the network, but it's unclear if that's related.
