推荐答案

看来这与Websockets无关，但是您似乎遇到了一个错误，该错误已在ejabberd存储库中修复，将被打包为16.03。

It seems this is not related to Websockets, but you seem to have hit a bug that is already fix in ejabberd repository and that will be packaged as 16.03.

如果您从ejabberd存储库更新到最新的HEAD，它将解决您的pubsub崩溃问题。

If you update to latest HEAD from ejabberd repository, it should solve your pubsub crash issue.
