My python file generate two child_process. When I run "pm2 start xxx.py",the program woks well. But when I close one child_process, another also paused.

What's going wrong?

My python file generate two child_process. When I run "pm2 start xxx.py",the program woks well. But when I close one child_process, pm2 will not reload the program. I just want to ask that could pm2 identify child_process and protect it when the program contains child_process?

How could we reproduce this issue?

import multiprocessing as mp

def fun1():
    while 1:
        print(11111)

def fun2():
    while 1:
        print(22222)

if __name__ == "__main__":
    read_process = mp.Process(target=fun1, args=())
    o_process = mp.Process(target=fun2, args=())
    read_process.start()
    o_process.start()

python 3.9

$ pm2 start test.py

Start by reproducing the Windows 11 case with Python 3.9 using the reported multiprocessing example and pm2 start test.py. Read the PM2 process-launch and child-process handling entry points to determine the current behavior; done means the issue has a documented or tested outcome for closing one child process while the other remains active.
