I have started a python script by following:

nohup python src/myscript.py &

Now there is a process running, where the PID is changing constantly, so it is absolutely not possible to kill it. When I try this one nohup process killing, it says the -sh: kill: (8792) - No such process.

Also tried to grep it by name and kill it, same issue, because the PID is changing constantly. As noted by @MarcusMüller in a comment, apparently this is because it constantly spawns new browser instances.

Really confused why nothing is working, restart did not work. Considering to reinstall whole system ...

    nohup doesn't change PIDs (try with nohup sleep 600). In fact, it's impossible to change PIDs at runtime as process. more likely, your script is forking/spawing a lot of subprocesses. What specifically does myscript.py do?

    impfbot continuously spawns new browsers. Of course you get new PIDs that way.

Assuming the process command appears like 'python src/myscript.py' in process listings such as ps, top, htop etc:-

killall -s STOP 'python src/myscript.py' would pause the processes; -s CONT would resume them,

To see all signals, killall -l, but sending TERM should terminate them - and ABRT should forcibly remove them.
