Sip.js: 警告：检测到可能的 EventEmitter 内存泄漏。添加了 11 个听众。使用emitter.setMaxListeners() 增加限制。

创建于 2018-06-07 · 8评论 · 资料来源: onsip/SIP.js

切换到 0.11.0 后，我现在在控制台中收到一个可能的 EventEmitter 内存泄漏错误。这是随错误提供的跟踪：
来自火狐：

EventEmitter.prototype.addListener    webpack://SIP/./node_modules/events/events.js?:138:7
InviteClientTransaction               webpack://SIP/./src/Transactions.js?:148:5
send                                  webpack://SIP/./src/RequestSender.js?:40:36
sendRequest                           webpack://SIP/./src/Session.js?:198:7
sendReinvite/<                        webpack://SIP/./src/Session.js?:466:9

从铬：

EventEmitter.addListener | @ | events.js:144
InviteClientTransaction | @ | Transactions.js:148
send | @ | RequestSender.js:40
sendRequest | @ | Session.js:209
(anonymous) | @ | Session.js:466
Promise.then (async) |   |  
sendReinvite | @ | Session.js:465
unhold | @ | Session.js:359

当我取消保持通话时会发生这种情况。如果我能提供更多信息，请告诉我。

是的，这似乎与运输工作有关。我们将一些职责转移到各个组件上，您看到的问题可能是相关的。我希望在星期一或星期二之前得到一个补丁。非常感谢您花时间追踪此事。

我在测试中没有看到这一点。为什么一切都说 raven.js 和行号并没有真正意义。您是否有一些可能导致此问题的自定义代码？

egreenmachine 于 2018-06-08

我正在使用Sentry进行日志记录，它使用 raven，这就是 raven.js 和第 55 行的来源。如果我禁用 Sentry，我仍然会收到相同的错误，而不是 raven 它是LoggerFactory.js:78 。软电话充当 salesforce 的 CTI 适配器，但即使在 salesforce 之外，我仍然收到错误消息。我在 0.10.0 中没有看到这个，所以我想知道它是否与传输更改有关。

i-kitchen 于 2018-06-08

新的事件侦听器已在内部添加到 SIP.js 以用于传输工作，因此这绝对可以解释您看到它的原因。这就是我们试图确定的。话虽如此，这只是一个警告，如果数量没有失控，可以放心地忽略它。

@JimGreenberg将调查在 SIP.js 中增加此限制，以便警告将在未来版本中消失。或者，您可以提交 PR 来解决此问题。谢谢

egreenmachine 于 2018-06-08

在进一步调查和增加听众人数后，我发现听众人数不断增加可能确实存在问题。在EventEmitter.js我添加了NodeEventEmitter.prototype._maxListeners = 15并且错误出现在几个 un-holds 说 16 个听众之后。然后我将它增加到 100 并在多次取消保持后得到相同的错误。该错误指出已添加 101 个侦听器。
