如何在selenium中释放关闭的chrome浏览器内存?

我写了一个多线程自动化程序,它使用了很多chrome浏览器 (可以重复) 含硒和碳。

我试着使用所有的东西,包括--incognito,“--disable application cache”,在打开另一个浏览器之前等待一秒钟, driver.Close() , .Quit() 和 .Dispose() . 下面是代码示例:

IWebDriver[] drivers = new IWebDriver[AUTOMATION_NUM];
int QUEUE_BROWSERS_TO_OPEN = 0;

Thread mainThread = new Thread(() =>
{
    for (int i = 0; i < AUTOMATION_NUM && !EXIT; i++)
    {
        ...
        Thread driverThread = new Thread(() => {
            ...
            ChromeOptions chromeOptions = new ChromeOptions();
            chromeOptions.AddArguments("--incognito", "--disable-application-cache"); // headless or non-headless

            IWebDriver driver = drivers[instance];
            driver = new ChromeDriver(chromeService, chromeOptions, TIMEOUT_FROM);
            ...
            ++QUEUE_BROWSERS_TO_OPEN;
            ...
            driver.Close();
            driver.Quit();
            driver.Dispose();
        });

        _machineThreads.Add(driverThread);
        driverThread.IsBackground = true;
        driverThread.Start();

        while (i < AUTOMATION_NUM && !EXIT)
        {
            Thread.Sleep(5000);

            if (QUEUE_BROWSERS_TO_OPEN > 0 && BROWSERS_OPEN < BROWSER_NUM)
                --QUEUE_BROWSERS_TO_OPEN;
        }
    }

    Thread endThread = new Thread(() =>
    {
        foreach (Thread machineThread in _machineThreads)
            machineThread.Join();

        ...
    });
    endThread.Start();
});
mainThread.Start();

并建议我的客户通过单击按钮执行以下代码来终止所有“chromedriver.exe”进程:

Process[] chromeDriverProcesses = Process.GetProcessesByName("chromedriver");

foreach (var chromeDriverProcess in chromeDriverProcesses)
    chromeDriverProcess.Kill();

但我的客户仍然在说,关闭和完成的自动浏览器的内存仍然存在?

任何可行的解决方案如何防止我的客户端的高端PC重新启动以释放Chrome内存或在再次使用自动化之前被冻结?还有别的选择吗?
