Selenium 使用量角器和量角器运行多个实例时出错

我是cucumber和量角器的用户，具有自动测试功能，我在配置多容量方面存在问题

当我的

计数大于10时，我看到下面的错误，但仅在Linux环境中。我可以设置计数>10个窗口而不会出现问题

config.js

const path = require("path");
const jsonReports = process.cwd() + "/reports/json";
const Reporter = require("../support/reporter_login2/reporter");

exports.config = {

      }
    },*/

        var chai = require('chai');
        chaiAsPromised = require('chai-as-promised');
        chai.use(chaiAsPromised);
        chai.should();
        global.expect = chai.expect;
        browser.ignoreSynchronization = true;
        browser.manage().window().maximize();
        require('babel-register');
        Reporter.createDirectory(jsonReports);
    },
    cucumberOpts: {

    }
};

帮帮我，伙计们，谢谢
 哪个数字大于10？Hi@DublinDev，15，但是windows没有这个问题。哈哈，不，对不起，我的意思是数字10的意义是什么，你设置了maxInstances吗？maxSessions？或者你在哪里设置这个数字？啊哈，对不起，我在计数中设置了10，但是maxInstances是20，maxSessions是60。配置文件在那里，不用担心！我对Cucumber或Linux不太熟悉，所以不确定我现在能提供多少额外帮助。当我有更多的空闲时间时，我可能会再看一看。哪个数字大于10？嗨@DublinDev，15，但是windows没有这个问题。哈哈，不，对不起，我的意思是数字10的意义是什么，你设置了maxInstances吗？maxSessions？或者你在哪里设置这个数字？啊哈，对不起，我在计数中设置了10，但是maxInstances是20，maxSessions是60。配置文件在那里，不用担心！我对Cucumber或Linux不太熟悉，所以不确定我现在能提供多少额外帮助。当我有更多的空闲时间时，我可以再看一看。
