How reset number of PiD

Question

One thread in my python program check CPU use, in big simplification it look like this:

import time
import commands
while 1:
    example=commands.getstatusoutput('iostat')
    time.sleep(1)

after few days of work, program stop working, because: "socket: too many open files" I use all PiD number

I know that i can change number in cat /proc/sys/fs/file-max, but i would like "reset" numer of PiD. It is possibile without reset of whole device?

Answer 1

import os
import signal

os.kill(pid, signal.SIGTERM) #or signal.SIGKILL 

you have to kill the processes...
