When a pingpong based protocol tries to perform a connection disconnect, it sends a sort of "logout" command to the server, unless the connection is deemed dead. But the disconnect might happen before pingpong data has been completely sent, in which case sending the "logout" will not work. Check the pingpong state and do not "logout" when data is pending. This was detected as a condition in fuzzing that triggered a debug assert in the pingpong sending.
