Selenium: WebDriverException: unknown error: Chrome failed to start: exited abnormally

[PascalGit1]

OS:
Linux
Selenium Version: 3.5.3
Browser: Chrome driver V2.33 , chrome version 62.03

I'm running Selenium tests from jenkins on a linux machine. For this i'm using the latest chromedriver, when I run my tests about 90% will succeed but maybe 1 in 10 of the tests it will randomly fail with the following error:

Error:

When rerunning the same test it will usually succeed the 2nd try so im not sure how i can reproduce this consitantly. I have a maven project and it is setup like the follow:

Driver class:

    public static WebDriver getDriver(BrowserType browser) {
        WebDriver driver = null;
        switch (browser) {
        case CHROME:
            System.setProperty(PROPERTY_DRIVER_CHROME, PATH_DRIVER_CHROME);
            System.setProperty("webdriver.chrome.logfile", "C:/Programs/eclipse Neon/workspace/cucumber/logs/chromedriver.log");
            System.setProperty("webdriver.chrome.verboseLogging", "true");
            driver = new ChromeDriver();
            break;
        case FF:
        default:
            FirefoxOptions options = new FirefoxOptions();
            options.setLogLevel(Level.WARNING);


            System.setProperty(PROPERTY_DRIVER_FIREFOX, PATH_DRIVER_FIREFOX);
            driver = new FirefoxDriver(options);
            break;
        }
        return driver;
    }

Exp. the same issue. @PascalGit1 were you able to resolve his?

[PascalGit1]

@bondib sadly not i made a post on the chromedriver usergroup located here:
https://groups.google.com/forum/#!topic/chromedriver-users/8yZDv_h8feg
but nobody has replied yet so im not sure if they are even looking at it

Hello guys,

I've been fighting with this issue for a long time, and just y'day I figure out how to make it gone and today I can run a 50 threads process calling selenium without seen this issue anymore and also stop crashing my machine with outofmemory issue with too many open chromedriver process.

1. I am using selenium 3.7.1, chromedrive 2.33, java.version: '1.8.0', redhat ver '3.10.0-693.5.2.el7.x86_64', chrome browser version: 60.0.3112.90;
2. running an open session with screen, to sure my session never dies,
3. running Xvfb : nohup Xvfb -ac :15 -screen 0 1280x1024x16 &
4. export DISPLAY:15 from .bashsh/.profile

this 4 items are the basic setting everyone would already knows, now comes the code, where all made a lot of difference to achieve the success:

public class HttpWebClient {
public static ChromeDriverService service;

public ThreadLocal<WebDriver> threadWebDriver = new ThreadLocal<WebDriver>() {

    @Override
    protected WebDriver initialValue() {
        FirefoxProfile profile = new FirefoxProfile();
        profile.setPreference("permissions.default.stylesheet", 2);
        profile.setPreference("permissions.default.image", 2);
        profile.setPreference("dom.ipc.plugins.enabled.libflashplayer.so", "false");
        profile.setPreference(FirefoxProfile.ALLOWED_HOSTS_PREFERENCE, "localhost");
        WebDriver driver = new FirefoxDriver(profile);
        return driver;
    };
};

public HttpWebClient(){
    // fix for headless systems:
    // start service first, this will create an instance at system and every time you call the 
           // browser will be used
           // be sure you start the service only if there are no alive instances, that will prevent you to have 
           // multiples chromedrive instances causing it to crash
    try{
        if (service==null){
            service = new ChromeDriverService.Builder()
            .usingDriverExecutable(new File(conf.get("webdriver.chrome.driver")))
            .usingAnyFreePort()
            .withEnvironment(ImmutableMap.of("DISPLAY", ":15"))
            .withSilent(true)
            .build();
            service.start();
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

public WebDriver getDriverForPage(String url, Configuration conf) {
    WebDriver driver = null;
    DesiredCapabilities capabilities = null;
    long pageLoadWait = conf.getLong("page.load.delay", 60);

    try {
            System.setProperty("webdriver.chrome.driver", conf.get("webdriver.chrome.driver"));
            String driverType = conf.get("selenium.driver", "chrome");

        capabilities = DesiredCapabilities.chrome();
        String[] options = new String[] { "--start-maximized", "--headless" };
        capabilities.setCapability("chrome.switches", options);

                    // here is where your chromedriver will call the browser
                    // I used to call the class ChromeDriver directly, which was causing too much problems 
                    // when you have multiple calls
        driver = new RemoteWebDriver(service.getUrl(), capabilities);

        driver.manage().timeouts().pageLoadTimeout(pageLoadWait, TimeUnit.SECONDS);
        driver.get(url);

                    // never look back

    } catch (Exception e) {
        if (e instanceof TimeoutException) {
            LOG.debug("Crawling URL : "+url);

BTW, I found a workaround by starting chrome at --no-sandbox mode (which is notbthe bewt practice). So it's a permission issue.

this is weird though. In one repo I use totally the same code with shippable for chromedriver and chrome itself as in another repo, and it's working fine without --no-sandbox and in another one it needs sandbox .. but thanks for this :)

I had the same problem: roughly 1% of selenium tests failed with:
org.openqa.selenium.WebDriverException: unknown error: Chrome failed to start: exited abnormally
(Driver info: chromedriver=2.29.461571 (8a88bbe0775e2a23afda0ceaf2ef7ee74e822cc5),platform=Linux 3.10.0-693.11.6.el7.x86_64 x86_64) (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 60.02 seconds

This happened only when running multiple tests in parallel on the same server.

The --no-sandbox option did not help me.

However, for some reason option --single-process helped and the problem went away.

I used this combination:
Chromedriver 2.29.461571 + Chrome 56.0.2924.87

But the problem occurred also with:
ChromeDriver 2.35.528139 / Google Chrome 63.0.3239.132
(but I did not test if the single-process flag helped with these versions)

Man, I noticed if I run selenium as super admin, then it doesn't work as the error message above.

But if I run selenium without sudo, then it works. Maybe it will help you. God bless you :)

People still having this issue and are desperate the only thing that seems to work is update to V2.35
Then add the following chromeoptions:
ChromeOptions ChromeOptions = new ChromeOptions();
ChromeOptions.addArguments("--headless", "window-size=1024,768", "--no-sandbox");
driver = new ChromeDriver(ChromeOptions);

It's not a great fix but it seems like it was the only thing that works for me.

[jaswennyhuangg]

in which file do we need to put --no-sandbox? can someone here give me the example?

[dankonino]

@jaswennyhuangg in wdio.conf.js at least that’s where I use it with web driver.io . 🍺
