      If the server returns an error when an exhaust cursor makes its initial query, a socket is leaked and the max_pool_size semaphore is never incremented:

      collection.find({'$bad_query_operator': 1}, exhaust=True)

      The bug is in both MongoClient and MongoReplicaSetClient.

      A network error on an exhaust cursor's initial query, on the other hand, is handled correctly in MongoReplicaSetClient, but causes a leak in MongoClient.

        There are no Sub-Tasks for this issue.
