Selenium 停止工作 java 浏览器

一个可执行的 jar 文件挂在 Linux 服务器上，即 Telegram bot。该程序全天候不间断工作，解析互联网上的链接。一切工作几天（2-3天）然后发生错误

之后，在我的情况下，在 geckodriver 上的 Firefox 中重新启动浏览器。重新启动后，一个新的错误飞了

但是它没有工作，而是连续多次启动浏览器，之后发生冲突。新打开的浏览器出现错误并且不关闭，但挂起工作，重新加载服务器

执行解析和启动浏览器的类本身

public class WebSurfing extends ArrayList<String>{

    public HashMap<String, String> connect(String url){
        HashMap<String, String> hm = new HashMap<>();

        System.setProperty("webdriver.gecko.driver", "/usr/bin/geckodriver"); // /usr/bin/geckodriver

        FirefoxOptions options = new FirefoxOptions();
        options.addArguments("--headless");

        WebDriver driver = new FirefoxDriver(options);

        try {
            url = url.replace("https://auto.ru/cars/", "https://auto.ru/moskva/cars/");
            driver.get(url);
            System.out.println("Connect to " + url);

            driver.findElements(By.xpath("//div[@class='button button_blue']")).get(0).click();
            System.out.println("After accept");

            Thread.sleep(10000);
            try {
               Document document = Jsoup.parse(driver.getPageSource());
               Elements elements = document.getElementsByClass("Link CardDealerName-module__dealerName");

               hm.put("Результат", elements.get(0).attr("href"));
               System.out.println(hm.get("Результат"));
               hm.put("Конкурент", elements.get(0).text());
               System.out.println(hm.get("Конкурент"));

            } catch (Exception e) {
                hm.put("Результат", " ");
                hm.put("Конкурент", " ");
                e.printStackTrace();
            }

        } catch(Exception ex){
            ex.printStackTrace();
        } finally {
            try {
                driver.close();
            } catch (Exception e){}
            try {
                driver.quit();
            } catch (Exception e){}
        }

        return hm;
    }
}

也许我做错了什么，怎么了？

    我将浏览器更改为 GoogleDriver，一切正常运行了 4 天。我用参数打开浏览器

    options.addArguments("--no-sandbox");
        options.addArguments("--headless");
        options.addArguments("--no-proxy-server");
        options.addArguments("--disable-gpu");
        options.addArguments("start-maximized");
        options.addArguments("disable-infobars"); 
        options.addArguments("--disable-extensions");
        options.addArguments("--disable-dev-shm-usage");

    机器人正在飞行。数据库正在工作。没有错误。确实，检查链接的速度是有限的，我认为这是因为我在每次请求之前打开和关闭浏览器，如果我只是关闭选项卡并打开一个新选项卡，它很可能会运行得更快。所以问题可能出在浏览器上，或者内存耗尽，也许 FirefoxDriver 在某些时候重载了服务器并且一切都失败了。但与此同时，FirefoxDriver 自己重新加载检查了 3-4 个链接，GoogleDriver 在这方面落后，可能是由于给定的参数。
