How to stop/cancel a background job ?

[AiroPi]

I just installed face recognition within community container from nextcloud AIO.
Face recognition started automatically, and now I'm unable to stop it. I want to assign 8GB of RAM instead of 4, but when I do php occ face:setup -M 8G -m 5, I only get :
Another command ('face:background_job') is already running that prevents it from continuing.

How can I stop it ?
