[internet-explorer] IE8 crashes when loading website - res://ieframe.dll/acr_error.htm

To prevent IE8 from going on an endless loop of refreshing and crashing it stops after two times and shows this url. There could be many issues that might be causing it to crash.

In my case an upgrade to jQuery v1.10.2 from v1.4.4 causing the issue, but it must have been mostly our code bad and was now more evident with the upgrade.

My observation was everything seems working fine on IE7/XP, IE8/Win7, IE9/Win7 and IE10/Win7 but was not working fine on IE8/XP and IE8/Server2003. The version of IE8 on Win7 and XP/Server 2003 are different. Here is the list of versions for each Operating System (http://support.microsoft.com/kb/969393).

Then looked at Event viewer on Win Server 2003 and it had something like faulting module mshtml.dll, version 8.0.6001.18975 and on Win XP it was faulting module mshtml.dll, version 8.0.6001.18702 even though the browser version is same on both which is 8.0.6001.18702.

Then further searching about this mshtml.dll, it looks like Microsoft keeps updating mshtml.dll which is the HTML component of the browser through patches. So then I realised its not the browser version that is important but mshtml.dll version instead.

So I went ahead and downloaded the latest Cumulative patch for IE8 from here (https://technet.microsoft.com/en-us/security/bulletin/ms13-059) which updated my mshtml.dll file (in system32 folder) to 8.0.6001.23515 and it started working fine , may be they fixed it some time back probably in this (http://technet.microsoft.com/en-us/security/bulletin/ms12-037)

But first things first always reset your browser so that you disable all plugins and rule out the possible cause by external plugins.
