I have seen tests where it looks like a client is receiving notifications that the server exited before receiving an ACK message on the command. This might be a symptom of the server exiting before all the messages in flights have been sent.
Reopening as an existing problem on exit command.
My guess is that we need to make the two roles switch to a receive-only/send-only mode for the last message supposed to be sent out.
