Why is terminating a process not working?

Question

Python

I am using multiprocessing .
In a simplified form, the code looks like this:

class MainProcess(mp.Process):
    def run(self):
        self.proc1 = mp.Process(target=function1, args=(....))
        self.proc2 = mp.Process(target=function2, args=(....))
        self.proc3 = mp.Process(target=function3, args=(....))
        self.proc4 = mp.Process(target=function4, args=(....))

    def terminate(self):
        self.proc1.terminate()
        self.proc2.terminate()
        self.proc3.terminate()
        self.proc4.terminate()

But the processes are not terminated, and the same thing is written to the database n times. Why is this happening?

Answer 1

No need to end processes. They need to know for themselves when they're done.
