Answer 1

To prune the workers manually, include the vendor/chrisboulton/php-resque/lib/Resque/Worker.php file, instantiate a Worker, then call pruneDeadWorkers();

<?php 
include 'vendor/chrisboulton/php-resque/lib/Resque/Worker.php'; // If you're not already using composer autoloader

$worker = new Worker('default'); // the argument doesn't matter
$worker->pruneDeadWorkers();

php-resque is not shipped with a function to restart workers, take a look at fresque for that.

To avoid having dead workers, compile your php with pcntl_fork , to execute your jobs in a fork, and isolating them from the workers.

Answer 2

first find worker list : Resque_Worker::all(); this contain workers id according to php-resque doc type in command line

`kill workers id`
