Issue with new Websocket Plugin

Hi,

i migrated my site to the new Websocket Plugin using Openfire 3.10.2 and stanza.io on the client side. The same setup works fine using BOSH. After switching to websockets the whole http-bind resource becomes unresponsive after ~ two hours uptime accepting no more new connections (neither BOSH nor Websockets). At this time there were only around 200 active users. I'm using nginx to proxy the websocket connections to openfire using this setup NGINX as a WebSocket Proxy - NGINX

Any thoughts on this issue?
