Queues with 0 processes

[eelco-weblog]

Version:
Laravel 8.0
Horizon 5.0
phpredis as client

Very often, we have queues with 0 processes. We see this in the dashboard, and we see this when I run app(Laravel\Horizon\Repositories\RedisSupervisorRepository::class)->all(); on the server. This leads to queues with thousands of unprocessed jobs. Sometimes the queues will get some processes again after a few hours, sometimes our memory just completely fills up because the processes wont start at all. The processes are started correctly, but over time the processes disappear.

I have attached some screenshots. I have started a topic at Laracast before but without response. We don't know whats the issue and don't know how to solve this. In the screenshots, I have removed the queue names to prevent some sensitive data becoming public.

Thanks for your reply! I posted to Laracasts 2 months ago:

I believe this is a bug, because a queue should never have 0 processes?

Please try some of the other channels first, thanks.
