jQuery Ajax call causing IE8 to crash when data returned from WCF service

I have created a WCF web service. I call this usinq jQuery 1.7.1

try { 
        type: "GET", 
        url: '/_vti_bin/PROJ/WCF.svc/GetDetails', 
        contentType: "application/json; charset=utf-8", 
        data: myid, 
        success: function (msg) { 
        error: wcfServiceGetFailed 
} catch (e) { 
    alert('error invoking service.get()' + e); 

This is working on all browsers when the results size is small. When the result size is bigger IE8 crashes. Chrome and IE9 work fine. The body of the json returned is 51,856(not sure what the units are in fiddler). IE crashes completely. It hangs and nothing is displayed. The IE process needs to be killed.

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: Open the link and click to "Fork" (in the top menu) to get started.

This bug tracker is not a support forum, and is only for solving reproducible, verifiable bugs with jQuery Core itself.

Please provide a jsfiddle testcase.

You'll need to debug this further so it can be shown to be a jQuery core bug. In any case that is a very large return, so it may just be that IE8 has some performance issue with a response that large.
