[bind10-dev] noisy failure of bind10

[Likun Zhang]

Jeremy,

I didn't try to reproduce the problem, just have the idea from the log message.

It's easy to reproduce the nossy failure of bind10, when we start bind10 in verbose mode and input "ctrl + c" to terminate bind10 immediately, since some process has not finished starting(I have no idea about how to fix it now).

>From the log message, " [b10-cmdctl] Error creating server, because: [Errno 48] Address already in use", I guess there is another b10-cmdctl process running, or the port 8080 is used by other process.

Did you start bind10 process with "brittle" mode? If true, I think it's the reason. B10-cmdctl can't be started properly, then bind10 try to kill all the other processes which are starting, then noisy come. 

Thanks
Likun
