multiprocessing - python多进程爬虫报错

Question

周末在家撸代码了,写了一个小脚本爬取alexa网上的top500的域名,使用了多进程,但是报错了,

Traceback (most recent call last):
  File "alexa.py", line 116, in <module>
    site.multiprocess()
  File "alexa.py", line 83, in multiprocess
    self.domain = multiprocessing.Manager().list()
  File "/home/rocky/python/lib/python2.7/multiprocessing/managers.py", line 667, in temp
    token, exp = self._create(typeid, *args, **kwds)
  File "/home/rocky/python/lib/python2.7/multiprocessing/managers.py", line 565, in _create
    conn = self._Client(self._address, authkey=self._authkey)
  File "/home/rocky/python/lib/python2.7/multiprocessing/connection.py", line 175, in Client
    answer_challenge(c, authkey)
  File "/home/rocky/python/lib/python2.7/multiprocessing/connection.py", line 432, in answer_challenge
    message = connection.recv_bytes(256)         # reject large message
IOError: [Errno 11] Resource temporarily unavailable
