How to restart a process using python multiprocessing module

Asked by At

I am trying to restart a python process using multiprocessing module, but "AssertionError: cannot start a process twice" appears.

My question

  • How can I restart the process
  • Once its terminated why it is going to zombie mod
  • How can I remove the zombie process
import time
from multiprocessing import Process

def worker ():
    while True:
        print "Inside the worker"
        time.sleep(10)


p1 = Process(target=worker,name="worker")
p1.start()
#p1.join()

time.sleep(3)

p1.terminate()
print "after Termination "
time.sleep(3)


p1.start()


Actually I am trying to create a process monitor function to watch the memory and CPU usage of all processes . If it reach a certain level I want to restart on realtime
