IllegalStateException ajax

 

Answer - The following was happening. I think i can put it down to a low impact issue.

It happens when the browser opens a Socket and makes an Ajax request however it then terminates the open Socket (by closing the browser or moving to another page) before receiving the response from the server. Meanwhile the server is processing the request and tries to write the output back to the browser however the browser has closed the Socket and moved on.
