李振海 commented on GUACAMOLE-1444:
--------------------------------
I have studied the "VNC" protocol for several days. It should be the "select"
mechanism. Libvncserver demo also has this problem. Theoretically, a heartbeat
mechanism should be needed to detect whether the other party exists, but I
don't know how to write it. I still need to study it
> After VNC network is interrupted, please disconnect
