> In some cases traffic_cop can't restart traffic_manager properly. We met these issues at "Ashmanov and partners" (http://en.ashmanov.com/). There are two places in code which in my opinion need corrections:
> 1) The logic which decides whether to kill process or group.
> 2) The main traffic_cop loop: it doesn't reinitialize manager API in case of failure and this fact leads to constant attempts to connect to manager using socket id == -1. 
> I have prepared patches for both issues. Please kindly take a look at them and let me know your thoughts.
