VIP hanging on Javascript

[jsgibbs1]

I am using client/server ssl authentication on a Standard VIP with iRules.

All worked fine on v12.x. After upgrading to v14.x, several customer websites now hang on different pieces of javascript; <jquery.modal.js> is one. The only way to get past is continuously keep reloading the browser. I'm seeing this behavior on 15.x as well, so I assume it's something F5 has changed since the v12.x days.

Any idea what might be causing this?

Can you see what is happening in the

Browser Developer Tools

Network tab

Is the request failing or is there a javascript error?

Sorry for the long delay. The Status goes to a pending state and remains there until you manually refresh it. Sometime requires multiple refresh before the page will load completely.
