ImageResizer - 免费版的OutOfMemoryException

Question

我在Asp.net应用程序中使用ImageResizer，我不时会看到OutOfMemoryException。 C＃代码非常简单：

var instruction = new Instructions { Width = width, 
                                     Height = height, 
                                     Format = null, 
                                     Mode = FitMode.Max }
(new ImageJob(source, destination, instruction)).Build();

计算机内存仅使用10％，我在监视工具中看不到内存问题。这是调试日志的一部分：

When fetching a remote license file (if you have one), the following information is sent via the querystring.

我看到了行When fetching a remote license file (if you have one), the following information。也许我需要升级到企业版？
