#17 camera fails to reconnect (socket level problem)

[Alex Monjushko]

When a camera is connected to the server, and the
server is terminated, the camera is supposed to
reconnect. It does manage to reconnect, but the
receiving side of the control channel on the camera does
not respond to any of the messages coming from the
server.

As you can see in the logs below, the camera
reconnects, and sends the "HELLO" command, to
which the server replies with an "OK," but the camera
never receives the response. Furthermore, in the GUI, if
you attempt to execute "GO," the message is not
received by the camera.
