Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'

Question

I know that there's already some post for this particular question but I can't figure out what I'm doing wrong. The error happens on this page : http://www.gentec-eo.com/products/thz-detectors, I can't reproduce it. I recieve an email that report this error 2 to 6 times a day, I've been looking for the solution for a while but I can't figure it out. One thing to notice is that it's always from the same ip : 72.14.199.4 witch I think is a google's bot. I don't get an innerexception. My code is pretty simple, the only thing that is different from the other pages is that I use Telerik's Grid to show the data with a jQuery post action.

Here's my error :

Message : Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'.

    }
    pageModel.CurrentCategory = currentCategory;
    BuildMenusAndBreadCrumb(pageModel);
    GetHeader(pageModel, currentCategory);
    ViewData.Model = pageModel;

    return View();

public virtual ActionResult ListProductCompare(string categoryName)
{

    var gridModel = new GridModel<ProductCompare>();
    gridModel.Data = _productCompareRepo.GetByCategory(categoryName);
    return View(gridModel);
}

Thanks a lot for the help!

Edited 2 :

I have an other InnerException but I still can't figure out what's my problem.

Unfortunately this stack trace doesn't help pinpoint the problem. I would recommend you logging the request url and parameters that were used to cause the exception. If you are using ELMAH you already have this information and if not you could perform this easily in the Application_Error handler in Global.asax. This way you will be able to identify the exact cause and reproduce the issue.
