主机继续运行python TCP套接字

Question

我目前正在为局域网做一个Python实用程序，目前，如果我重复运行该程序，它会间歇性地抛出此错误。

Traceback (most recent call last):
  File "netbin.py", line 49, in <module>
    results = pool.map(ping, pAddress)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/pool.py", line 225, in map
    return self.map_async(func, iterable, chunksize).get()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/pool.py", line 522, in get
    raise self._value
socket.error: [Errno 64] Host is down

这个问题可能会继续出现吗？
