ruby on rails - How do I clear stuck/stale Resque workers?

Question

As you can see from the attached image, I've got a couple of workers that seem to be stuck. Those processes shouldn't take longer than a couple of seconds.

I'm not sure why they won't clear or how to manually remove them.

I'm on Heroku using Resque with Redis-to-Go and HireFire to automatically scale workers.

Answer 1

None of these solutions worked for me, I would still see this in redis-web:

0 out of 10 Workers Working

Finally, this worked for me to clear all the workers:

Resque.workers.each {|w| w.unregister_worker}
