[one-users] noVNC error: "Server disconnected" [socket.error: [Errno 98] Address already in use] ?

[Hector Sanjuan]

Hello, I don't get to reproduce this. I close and reopen repeted times the  
VNC window and it works well.

When you close the vnc window, you should be seeing a line like and the  
stopvnc action pop up message:

Thu Apr 05 10:15:21 2012 [I]: 127.0.0.1 - - [05/Apr/2012 10:15:21] "POST  
/vm/12/stopvnc HT
TP/1.1" 200 - 0.0610

Could you check that this request happens and that it acknowledged with  
200?

Thanks,

Hec
