Selenium 集线器/节点因 CLIENT_STOPPED_SESSION 而终止

问题描述

并行运行多个网络驱动程序

集线器的配置：

browserTimeout : 120
debug : false
jettyMaxThreads : 250
host : 172.31.4.15
port : 4444
role : hub
timeout : 1800
cleanUpCycle : 5000
capabilityMatcher : org.openqa.grid.internal.utils.DefaultCapabilityMatcher
newSessionWaitTimeout : -1
throwOnCapabilityNotPresent : true
registry : org.openqa.grid.internal.DefaultGridRegistry

浏览器配置

browserTimeout: 120
debug: false
jettyMaxThreads: 250
host: 172.31.0.29
port: 5555
role: node
timeout: 1800
cleanUpCycle: 5000
maxSession: 1
capabilities: Capabilities {applicationName:,browserName: chrome,maxInstances: 1,platform: LINUX,platformName: LINUX,seleniumProtocol: WebDriver,server:CONfig_UUID: 68ec37b7-2311-4703-b6d5-314...,version: 87.0.4280.66}
downPollingLimit: 2
hub: http://selenium-hub:4444/grid/register
id: http://172.31.0.29:5555
nodePolling: 5000
nodeStatusCheckTimeout: 5000

register: true
registerCycle: 5000
remoteHost: http://172.31.0.29:5555
unregisterIfStillDownAfter: 60000

10 个镀铬节点， 不同的版本 81、87、88 和 89， 没有镀铬选项。

我尝试增加 browserTimeout、timeout 和 jettyMaxThreads 当我需要生成一个新的测试/蜘蛛时，一些测试/蜘蛛运行得很好，我得到以下异常：
