res.render在調用fs.stat/fs.access之後導致本地err

我正在嘗試爲我的站點的一個子集構建一個catch-all路由，其中包含需要由ejs處理的多個目錄/頁面，但不需要特定的路線。res.render在調用fs.stat/fs.access之後導致本地err

[NB，我包括在下面的例子中，同步版本，以除去在相同的行爲的結果的定時的任何問題...的類似實施fs.stat的（和fs.access的）]

router.get('/foobar/:page(*)', function(req, res, next) { 

    var fs = require('fs'); 
    var path = require('path'); 
    var viewsPath = req.app.get('views'); 

    try 
    { 
     // see if there's an ejs file corresponding to request 
     var stats = fs.statSync(path.join(viewsPath, 'foobar', req.params.page + '.ejs')); 
     console.log(stats); // stats object seems accurate 

     // THROWS WHEN CALLING openSync 
     res.render('foobar/' + req.params.page, {title: 'foo'}); 
    } 
    catch (e) 
    { 
     var err = new Error(); 
     err.status = 404; 
     next(err); 
    } 
}

404路工作得很好，但是當我要求實際存在的網頁，渲染調用拋出：

它的行爲幾乎像fs.statSync呼叫已放置在文件的鎖在t時呈現扼流圈試圖打開視圖文件。

occams剃刀：我正在使用的測試頁有一個無效的包含路徑引用！它並不是抱怨我試圖加載的模板，而是一個引用它的模板。
