我的网站有时会被阻止并且每隔几次都无法正常工作（有时它可以正常工作很长时间，使用相同的代码），得到我在下面显示的日志。每次发生这种情况，我必须去我的控制台，刷新缓存，并将前端实例类的应用程序设置从 F1 更改为 F2 或 F4 以使第一次加载成为可能，一旦完成，又改回 F1 （在第一次请求后完美运行）。但过了一会儿，我又遇到了服务器错误，我的网站无法正常工作。

I 2013-09-06 17:07:03.131
This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.
W 2013-09-06 17:07:03.131
A problem was encountered with the process that handled this request, causing it to exit. This is likely to cause a new process to be used for the next request to your application. If you see this message frequently, you may be throwing exceptions during the initialization of your application. (Error code 104)
在我的本地环境中，我没有遇到这个问题。看起来spring框架和gae使用的缓存之间存在某种问题，但不知道这里发生了什么......请有什么建议吗？
它看起来也与前端实例有关，我想我在第一个请求之后总是有一个，但由于某种原因，有时会关闭，我必须再次更改为 F4 选项才能使其工作，否则我得到服务器错误。
从日志来看，objectify 可能会引发某种异常，我使用的是 4.0b2 版本
我还在该部分的应用引擎中发现了一个相关的错误："ApiProxy$CancelledException: The API call memcache.Get() was explicitly cancelled."
