Solve the following python programming problem given the following code:
def _run_server() : 
    host = cfg.CONF.stream.host 
    port = cfg.CONF.stream.port 
    LOG.info ('(PID=%s) ST2 Stream API is serving on http://%s:%s.', os.getpid (), host, port) 
    max_pool_size = eventlet.wsgi.DEFAULT_MAX_SIMULTANEOUS_REQUESTS 
    worker_pool = eventlet.GreenPool (max_pool_size) 
    sock = eventlet.listen ((host, max_pool_size)) 
    def queue_shutdown(signal_number, stack_frame) : 
        eventlet.spawn_n (shutdown_server_kill_pending_requests, sock = sock, worker_pool = worker_pool, wait_time = WSGI_SERVER_REQUEST_SHUTDOWN_TIME) 
register_stream_signal_handlers (handler_func = queue_shutdown) 
    wsgi.server (sock, app.setup_app (), custom_pool = worker_pool) 
    return 0 

    
    

    Fix the buggy line: sock = eventlet.listen ((host, max_pool_size))

#Here is Python program to fix the buggy line: sock = eventlet.

sock = eventlet.listen ((host, port))
