How to exit from artisan worker on disconnected beanstalk correctly?

I'm using laravel 5.1 with beanstalkd mantained with supervisor.

The trouble is: 1) artisan queue:work beanstalkd --sleep=3 --tries=3 --daemon 2) sudo service beanstalkd stop

Thats all. I got 400G of errors in my laravel.log during 24h:

[2015-10-06 17:09:18] local.ERROR: exception 'Pheanstalk\Exception\ConnectionException' with message 'Socket error 111: Connection refused (connecting to localhost:11300)' in /home/glue/proj/crowdbanner/vendor/pda/pheanstalk/src/Socket/NativeSocket.php:45

How to avoid this correctly and stop worker when beanstalk is dead?
