我正在使用 selenium、chromedriver、facebook/php-webdriver 但是服务器总是在出错后挂起 可能是什么问题？硒还是php？
这是php错误：
Fatal error: Uncaught Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"w3c":false,"binary":"","args":["--no-sandbox","--headless","--disable-gpu"]}}} Operation timed out after 51627 milliseconds with 0 out of -1 bytes received in /var/www/html/php-selenium/vendor/facebook/webdriver/lib/Remote/HttpCommandExecutor.php:297 Stack trace: #0 /var/www/html/php-selenium/vendor/facebook/webdriver/lib/Remote/RemoteWebDriver.php(144): Facebook\WebDriver\Remote\HttpCommandExecutor->execute(Object(Facebook\WebDriver\Remote\WebDriverCommand)) #1 /var/www/html/php-selenium/s.php(19): Facebook\WebDriver\Remote\RemoteWebDriver::create('http://localhos...', Object(Facebook\WebDriver\Remote\DesiredCapabilities), 50000, 50000) #2 {main} thrown in /var/www/html/php-selenium/vendor/facebook/webdriver/lib/Remote/HttpCommandExecutor.php on line 297

6月29日更新，我已经将chromdriver更新到75.0.3770.90，但问题依旧。没有什么变化。

我已经解决了这个问题，使用“top”命令，我看到一个名为 kswapd0 的进度消耗了太多 CPU。这是一个与交换有关的进展，所以我在/etc/sysctl.conf中添加了这一行：vm.swappiness=5并获得了更多的RAM，该服务已经运行了一天。并且不再挂起。我没有意识到 1.8GB RAM 对于默认配置的 chrome 来说是不够的。
