是什么导致我的TPL任务停止运行？

Question

I have the following code:

while (true)
{
    Task.Run(() =>{
        var request = WebRequest.Create("url1");
        request.GetResponse();
    });

    Task.Run(() =>{
        var request = WebRequest.Create("url2");
        request.GetResponse();
    });

    Thread.Sleep(15000);
}

The idea is every 15 seconds invoke a couple of endpoints. It works fine for around 20 mins then eventually the code in the tasks never run. No errors. Have I created too many tasks? There are no out of memory issues either.

从@AlexeiLevenkov给出的注释中得到提示，该注释从request.GetResponse获取对响应对象的引用，然后关闭响应以解决此问题。
