Who's running my queued jobs on Forge? :-o

Hey everyone, it's kinda funny, but I feel more kinda sad about it. ?

I have a server at Laravel Forge and started using Redis Queue, to use Horizon, some months ago. I have to say that I've got like zero experience with server stuff and to have "more control" about queued jobs, I want to have them back in the database. So I rolled out an update, deleted the "Daemon" in Forge and switched in my .env to QUEUE_DRIVER=database.

I currently have no queue worker settled up in Forge but my queued jobs are still processed and I don't really know who's doing this (which process)...

ps aux | grep php output:

forge    11030  0.1  3.8 495544 39304 ?        S    18:27   0:00 php-fpm: pool www
forge    11031  0.0  3.8 495348 39012 ?        S    18:27   0:00 php-fpm: pool www
forge    11230  0.0  0.0  14856   928 pts/0    S+   18:31   0:00 grep --color=auto php
root     30452  0.0  3.3 488960 33516 ?        Ss   Feb09   0:34 php-fpm: master process (/etc/php/7.3/fpm/php-fpm.conf)

redis-cli monitor is just saying OK, also when I fire an queued email or so.

Any ideas how to get to know which process is running that jobs?
