如何解决selenium网格中的FORWARDING_TO_NODE_FAILED问题

Question

我已经在selenium网格上工作了几天了。我在同一台机器上为android创建了集线器和节点。节点正在集线器上注册，执行也开始了。但是过了一段时间，会话失败了，执行也停止了。很少有2-3个测试用例被执行。

请查看下面的错误日志以供参考

传入params -e ZALENIUM_EXTRA_JVM_PARAMS="-Dwebdriver.http.factory=apache"，，如下所示：

ZALENIUM_EXTRA_JVM_PARAMS="-Dwebdriver.http.factory=apache“运行--rm -t --name zalenium -p 4444:4444 -e docker -v /var/ run /docker.sock:/var/run/docker.sock...

它已经解决了，也在这里讨论过：https://github.com/zalando/zalenium/issues/593
