node.js - Nodejs 类型错误 : Cannot read property 'chId' of undefined

Question

我有 Omegle 克隆聊天服务。在压力下，我的nodejs(超过150个用户)崩溃并出现错误“TypeError:无法读取未定义的属性'chId'”。

/home/kotka/randomi.fi/beta/varaserver2/channel.js:67
        f = this.channels[e].chId;
                      ^
TypeError: Cannot read property 'chId' of undefined

    at Socket.ondata (http.js:1506:22)
    at TCP.onread (net.js:374:27)
