如何调试抛出此错误的应用程序:

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
Trace
    at Socket.EventEmitter.addListener (events.js:160:15)
    at Socket.Readable.on (_stream_readable.js:653:33)
    at Socket.EventEmitter.once (events.js:179:8)
    at TCP.onread (net.js:527:26)

我无法找到假定的泄漏对象来增加侦听器限制 .setMaxListeners(0);

解决方案(来自fardjad和jan salawa)

随着jan salawa的搜索,我找到了一个工作库(longjohn)来增加堆栈跟踪的详细信息.随着fardjad的回应我发现我们必须原型EventEmitter.addListener 和 EventEmitter.on.

通过该解决方案,我可以得到这个新的痕迹:

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.
