Question

几天前，我们开始在ASP.NET MVC应用程序的Elmah错误日志中收到以下错误：

堆栈不足以安全地继续执行程序。这个可以因为在调用堆栈或函数上有太多函数而发生堆栈使用了太多的堆栈空间。

有问题的应用程序是在Web场中的2台Windows Server 2012服务器上运行的多租户Web应用程序。在任一服务器上定期（每小时1或2次）发生错误，但始终在同一租户URL上。我们已经设置了具有相同设置（主题等）的另一个租户，但无法复制错误。它从未发生过。

异常和堆栈跟踪表明正在执行某种递归函数。在堆栈跟踪的开头：

System.Web.HttpException（0x80004005）：执行处理程序的子请求时出错 'System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper'。 ---＆GT; System.Web.HttpException（0x80004005）：执行处理程序的子请求时出错 'System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper'。 ---＆GT;

在我们到达调用堆栈中的下一个项目之前，这会重复85次。

然后我们有以下内容：

的堆栈跟踪

at ASP._Page_Themes_Clik_Views_Shared__Layout_cshtml.Execute（）in   c：\ MySite \ wwwroot \ Themes \ Clik \ Views \ Shared_Layout.cshtml：第15行
  在System.Web.WebPages.WebPageBase.ExecutePageHierarchy（）at   System.Web.Mvc.WebViewPage.ExecutePageHierarchy（）

同样重复85次，好像视图是递归执行的。

它指向的代码行是对Html.Action的调用：

public MvcHtmlString Menu(string name, string overrideView = null)
{
    Ensure.Argument.NotNullOrEmpty(name, "name");
    return html.Action("_details", "menus", new { name = name, viewName = overrideView });
}

这与显示网站导航菜单的所有其他租户和主题使用的代码相同。 MenusController：

[HttpGet]
public async Task<ActionResult> Details(string name)
{
    var menu = await menusClient.GetMenuByName(
        siteId: siteContext.SiteId,
        name: name
    )
    .ConfigureAwait(false);

    if (menu == null)
    {
        return HttpNotFound();
    }

    var model = Mapper.Map<MenuDetailsModel>(menu);
    model.SetCurrentMenuItem(Request.Url);           
    return View("Details", model);
}

#region Widget 

[HttpGet, ChildActionOnly]
public ActionResult _Details(string name)
{
    return Details(name).Result; // this is converted to a partial view result by an action filter
}

由于ASP.NET MVC不支持异步子操作，因此我们必须在_Details中对我们的异步操作进行阻塞调用。请注意，我们有一个操作过滤器，负责将ViewResult从Details转换为PartialViewResult。

正如我所说，这段代码在开发和生产（几乎所有时间）中都能正常工作。我试过在MenusController内抛出异常，但我仍然无法复制异常。

试试这个：

public static MvcHtmlString Menu(this HtmlHelper helper, string name, string overrideView = null)
{
    var url = new UrlHelper(htmlHelper.ViewContext.RequestContext);
    Ensure.Argument.NotNullOrEmpty(name, "name");
    return url.Action("_details", "menus", new { name = name, viewName = overrideView });
}
