Timed out waiting for driver server to stop

Question

I have written a scrapper using selenium which uses chrome driver. It works well but some time it fails to quit chrome driver with following exception

org.openqa.selenium.WebDriverException: Timed out waiting for driver server to stop.

Code I am adding my code here.

public class SeleniumScraper {

    private WebDriver driver;

    public SeleniumScraper() {
        WebDriverManager.chromedriver().setup();
        ChromeOptions options = this.getDefaultChromeOptions();
        this.driver = new ChromeDriver(options);
        driver.manage().window().maximize();
    }

    public WebDriver getPage(String url) {
        this.driver.get(url);
        return driver;
    }

    public boolean quitDriver() {
        this.driver.quit();
        return true;
    }

    protected ChromeOptions getDefaultChromeOptions() {
        HashMap<String, Object> chromePrefs = new HashMap<>(2);
        chromePrefs.put("profile.default_content_settings.popups", false);
        ChromeOptions options = new ChromeOptions();
        options.setExperimentalOption("prefs", chromePrefs);
        options.setHeadless(true);
        return options;
    }
}

I tried

   driver.close();
   driver.quit();

it does not throw any exception now.
