我们在Selenium Grid中不断面临浏览器超时问题。发生是间歇性的。我们无法找到原因。
如果有人有任何想法，那将有很大帮助。

这在很大程度上取决于硒网格配置。在您的配置 json 中可见，您已使用该属性maxSession请将其更改为maxInstances。不应限制网格上的最大会话数。即使你想保留这个属性，也要让它像1000左右。
还要消除属性newSessionWaitTimeout。让我们使用默认配置的值。
因为我们了解使用硒网格的唯一问题是维护，因为它需要在集线器和节点的基础上定期重新启动。我建议使用一些第三方包装器，以便更好，更轻松地维护。你可以试试Groupon的SeleniumGridExtras。
