    Description

      Posted as a question on Stack Overflow: http://stackoverflow.com/questions/20200179/mongoreplicasetclient-fails-unexpectedly-during-primary-re-election

      Attempt to insert document into database during primary election using MongoReplicaSetClient leads to AssertionError:

      Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/home/zero323/.virtualenvs/mg/local/lib/python2.7/site-packages/pymongo/collection.py", line 360, in insert
      self.database.connection)
      File "/home/zero323/.virtualenvs/mg/local/lib/python2.7/site-packages/pymongo/mongo_replica_set_client.py", line 1491, in _send_message
      member.pool.maybe_return_socket(sock_info)
      File "/home/zero323/.virtualenvs/mg/local/lib/python2.7/site-packages/pymongo/pool.py", line 397, in maybe_return_socket
      assert sock_info not in (NO_REQUEST, NO_SOCKET_YET)
      AssertionError

      Possibly related to https://jira.mongodb.org/browse/PYTHON-594?jql=text%20~%20%22AssertionError%22

      Steps to reproduce:

      • connect to 3 member replica set using MongoReplicaSetClient
      • kill primary
      • attempt to insert document before re-election is finished

      Tested with pymongo 2.6.3 and pymongo 2.6+ (b62750971c93152e69fc560afe9b7face24d46f8).
