This script will run tests repeatedly and can help uncover the error:

#!/bin/bash
while : 
do
    sudo py.test unit_tests/test_socket_connection.py
    if [ $? -ne 0 ]; then
        break
    fi  
done

Haven't come across this error anywhere.
I don't think this is still relevant. Otherwise reopen.
