检测到可能的 EventEmitter 内存泄漏

问题描述

我收到以下警告:

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
Trace:
    at EventEmitter.<anonymous> (events.js:139:15)
    at EventEmitter.<anonymous> (node.js:385:29)
    at Server.<anonymous> (server.js:20:17)
    at Server.emit (events.js:70:17)
    at HTTPParser.onIncoming (http.js:1514:12)
    at HTTPParser.onHeadersComplete (http.js:102:31)
    at Socket.ondata (http.js:1410:22)
    at TCP.onread (net.js:354:27)

我在 server.js 中写了这样的代码:

I wrote code like this in server.js:

http.createServer(
    function (req, res) { ... }).listen(3013);

如何解决这个问题?

推荐答案

这在 节点 eventEmitter 文档

这是什么版本的Node?你还有什么代码?这不是正常行为.

What version of Node is this? What other code do you have? That isn't normal behavior.

简而言之就是:process.setMaxListeners(0);

另见:node.js - request - 如何emitter.setMaxListeners"()"?
