We have some XHR on our website, that is reported in Google developer tools' network timeline as Receiving for 16035.5 days. There actually is a response, and for sure it does not take as long as reported ;)
I reviewed the HTTP headers and to me everything looks fine. That problem is not occurring temporarily but consistently for the same XHR. What's even more strange: If I do the same GET directly instead of using AJAX, the timing is reported correctly.
What could be the reason for this? I suspect some faulty response, but I can not see anything not normal.
