Question

I have a web application in ASP MVC 3. In development environment, everything works fine, in a production environment there is a page which throws a 500 error but not every time. For example when open this page for the first time it works, but when I do it 3 times it throws this 500 error.

I thought that maybe it could be a timeout issue, so I added this code in the web.config file:

<httpRuntime executionTimeout="3600" maxRequestLength="2147483647" />

but it didn’t solve the problem.

Any suggestions ?

EDIT

This is the action that calls the partial view :

public ActionResult _PopupDiscussion(int? id)
    {
        ViewBag.id = id == null ? null : id;
        return PartialView("PartialViews/_PopupDiscussion");
    }

then inside the partial view there is an AJAX request which calls this action:

public ViewResult PopupDiscussion_Content(DiscussionModelView model, int? id)
    {
        ViewBag.id = id;
        // some code here
        return View(model);
    }

I tried to turn off custom errors like this :

<system.web>
    <customErrors mode="Off"/>
</system.web>

but it didn’t work.

This was caused by calling an action inside the controller from a partial view.
I modified this by using @Html.Partial() instead of @Html.Action() and everything works just fine
