After multi-channel connection with windows, Several channels of session are connected. Among them, if there is a problem in one channel, Windows connects again after disconnecting the channel. In this process, the session is released and a kernel oop can occurs while processing requests to other channels. When the channel is disconnected, if other channels still exist in the session after deleting the channel from the channel list in the session, the session should not be released. Finally, the session will be released after all channels are disconnected.
