Debugging Nodejs SocketIO server

I upgraded to the latest nodejs on Windows 8 and my socketIO server launches but I can't send messages to it.

Running node

v0.10.31

When my server is running I correctly see 'handshake authorized' in the command console when I launch my web browser but I also see the 3 following messages which repeat every 10 seconds or so

debug - setting poll timeout
debug - discarding transport
debug - cleared close timeout for client foo

Is this normal? Or does this indicate something is wrong with my socketIO connection?
