Find any running "queue:listen" processes for a Laravel project and kill those. Fire "php artisan queue:stop" in your "current" project root. Intended to use with a deploy script when you are using non-daemon listeners and deploy releases. If you are using daemons, run "queue:restart" instead. You can use a process monitoring tool like Superviso…

Is this a graceful termination? Will it allow currently processing jobs to finish?
