Interesting observation. The code for waiting for valid port file values basically looks like

    for (int i = 0; i < 10; i++) {
        checkPortFile();
        if (successful)
            break;
        sleep(500);
    }

so the fact that it even reaches 6676 ms looks suspicious when it comes to load.
