Last week we started getting a timeout / 9997 error for a page on our site when testing with IE8. Other pages work fine and other browsers work fine. The error only affects the first view of the page, repeat view seems to work OK as well.
Here is a sample run showing the problem: http://www.webpagetest.org/result/131007_HH_RX0/
The page is http://www.pearl.com/sip/law
We run a private WebPageTest instance and the timeout problem occurs here as well as at webpagetest.org.
I’ve tested the page using a couple of different IE8 instances (8.0.6001.18702 on XP and 8.0.7601.17514 on Server 2008) and the page appears to load correctly.
When I watch the test run via the agent I can see the page fail to load and it looks like the test is aborted after a couple of minutes. Loading the page on the same box with the webpagetest agent not running works fine.
Is there anything else I can do to diagnose this or is there a problem with the agent?
