After running a very simle demo app (http://sinatra-sse.herokuapp.com) for a while on IE8, IE9, chrome and firefox I got this error message from IE8 (using DebugBar).
It happens from time to time but not often, I have no idea how to reproduce it, I just letting the browser open for a while.

The error is at line 48 character 11 (according to DebugBar)
