Can you confirm this fixes the problem you are seeing?

984fd7d should fix this.

We haven't released this to npmjs.org yet, but will soon.

This is a know bug of socket.io, a fix would require significant redesign of socket.io internals. See socketio/socket.io#952. I am afraid this issue is not going to get fixed anytime soon.

I'd recommend you setup a load-balancer that supports session affinity (sticky sessions), e.g. HAProxy.
