Selenium集线器失去与并行执行失败的节点之一的连接
我有一个问题在执行我的testing并行使用docker容器与selenium网格，虽然testing运行良好的串行。 但是当我在firefox和chrome上并行运行testing时，testing会停在中间，下面的例外。 我已经debugging，发现刚刚一个屏幕导航selenium毂容器丢失连接到Firefox的节点，但他们的行动正在执行的铬节点，它也是如此。 任何想法为什么连接丢失FF？ 请帮忙。 org.openqa.selenium.StaleElementReferenceException：陈旧元素引用：元素未附加到页面文档org.openqa.selenium.WebDriverException：未知错误：元素在点（84,913）处不可点击。
我不明白为什么这个问题在并行执行中发生。 我粘贴我的testng.xml和下面的错误
