While attempting to shutdown services using
command, the shutdown process hangs.
Currently if the supervise service is down on the given server, this command can hang.
A low priority feature request to handle this is being reviewed. It may make it to the future releases.
Until there's a change, the only workaround is to write a script to check if Imply Supervise Service is running (or check manually) before calling bin/service --down command.
