--concurrency=10 -n worker3.example.com Stopping the worker Shutdown should be accomplished using the TERM signal. When shutdown is initiated the worker will finish all currently executing tasks before it actually drastic (like sending the KILL signal). If the worker won’t shutdown after considerate time, for example because of tasks stuck in an infinite-loop, you can use the KILL signal to force terminate the worker lost (unless the tasks have the acks_late option set). Also as processes can’t override the KILL signal, the worker will not be able to reap its children, so make sure to do so manually. This command usually
