ASP.NET MVC兒童行動 - 堆不足，無法繼續執行程序安全

Question

前幾天，我們開始收到以下錯誤在我們的ASP.NET MVC應用程序ELMAH錯誤日誌：

不足棧繼續安全地執行程序。這可能是 發生在調用堆棧上的功能太多或者功能太多，堆棧空間太多。

有問題的應用程序是在Web場中的2個Windows Server 2012服務器上運行的多租戶Web應用程序。在任一服務器上定期發生錯誤（每小時1或2次），但始終在同一租戶URL上。我們已經建立了另一個擁有相同設置（主題等）的租戶，但無法複製該錯誤。它從未發生過發展。

異常和堆棧跟蹤指示某種正在執行的遞歸函數。在堆棧跟蹤的開頭：

System.Web.HttpException（0X80004005）：錯誤執行的處理程序 'System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper' 子請求。 ---> System.Web.HttpException（0x80004005）：爲處理程序 'System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper'執行子請求時出錯。 --->

這樣重複85次，纔得到調用堆棧中的下一項。

然後我們有以下幾點：

從堆棧跟蹤：

在 c。在ASP._Page_Themes_Clik_Views_Shared__Layout_cshtml.Execute（）：\ mysite的\ wwwroot的\ \主題的Clik \ Views \ Shared_Layout.cshtml：line 15
at System.Web.WebPages.WebPageBase.ExecutePageHierarchy（）at System.Web.Mvc.WebViewPage.ExecutePageHierarchy（）

類似地重複85次，就好像視圖是遞歸執行自己一樣。

的代碼行它指向的是Html.Action呼叫：

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

這是由所有的其他住戶和主題顯示的網站導航菜單相同的代碼。 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 
} 

因爲ASP.NET MVC不支持我們不得不作出一個阻塞調用我們的異步操作中_Details異步孩子的行爲。請注意，我們有一個操作過濾器，負責將ViewResult從Details轉換爲PartialViewResult。

正如我所說的，這段代碼在開發和生產（幾乎所有時間）都能正常工作。我試過在MenusController內拋出異常，但我仍然無法複製異常。

試試這個：

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 }); 
}
