Laravel Forge, Queues, Keep restarting

I have a Laravel Application set up, with a number of jobs that are queued. So In forge, I set up the Queue's but none of the workers seem to stay alive for more than 20 seconds.

I'm not sure if this is normal behaviour, but if I view the status of them with the forge Check Worker Status button, I can see a number of them starting up, others with an uptime of only 12 seconds. If I close and open it again, then others have dropped and are Starting up. They never seem to stay up long enough to process anything in my Queue.

Is this normal? What could be killing my workers? I have tried running them with the daemon option ticked and without but to no avail.

So if I look at the server logs, this is what they show:

supervisord 2020-01-30 10:57:45,709 INFO exited: worker-271276_16 (exit status 0; expected)
supervisord 2020-01-30 10:57:45,821 INFO spawned: 'worker-271276_16' with pid 15287

supervisord 2020-01-30 10:57:48,253 INFO exited: worker-271276_14 (exit status 0; expected)

Is this normal? Why would they exit and restart?
