Please help me out to understand the ejabberd log and how can I make the successful websocket connection from client to ejabberd.

回答1:

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.

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