I cannot launch DelayedJob as soon as I start my VPS on Ubuntu 22.04.

I have tried several solutions to launch it and it succeeds, but once it has launched all the remaining jobs, it exits automatically, but I would like it to be constantly open.

I tried via Crontab (with @reboot), via services (with delayed_job start and script.sh), via Foreman, I don’t have any errors but it always quits on its own… Note that if I run exactly the same command in my process, DelayedJob remains fine open even if there are no jobs to process.

Thanks for your help.
