Unexplained Timeout

http://www.webpagetest.org/result/110803_T2_17GBM/1/details/

I can’t figure out why i’m getting an error on this test. I’m not able to replicate from the desktop - but it seems like a connection is hanging open or something prior to document complete on the Dulles Agent? Any ideas?

It’s timing out because onLoad never fired. If you go to the screen shot page it also includes the browser status messages which can some times give you a clue: http://www.webpagetest.org/result/110803_T2_17GBM/1/screen_shot/

In this case it says:

Thanks Pat.
