I've looked at the logs, and see a really weird situation.
2015-08-07T14:04:56 - deployment is starting (after upgrade)
2015-08-07T14:56:48 - deployment is finished, message sent to nailgun
2015-08-07T14:56:48 warning: [630] Trying to reconnect to message broker. Retry 5 sec later...
2015-08-10T09:02:13 - stop comes, nothing to stop, so message is skipped by all the workers
Basically the problem is Nailgun haven't received a message, there is nothing in reciever log about that.
