How to kill Zombie process?

[张少驰]

  When I use ret=os.fork(),it will create a parent process and child process,when child process exists,it will creaet a Zombie process,How to kill it in parent's process? For example:

udpSerSock=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
while 1:
  message=recvfrom(BUFSIZ)
  ret=os.fork()
  if ret==0:
     udpSerSock.close()
     ip=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
     #something deal
     ....
     ip.close() 
     break

#ps -a
I will find a Zombie process
