我得到以下错误。
com.google.apphosting.api.ApiProxy$RequestTooLargeException：对API调用datastore_v3.Put（）的请求太大。
我使用的是Objectify 4.0，没有上传任何文件。我正在为我的应用程序使用DataStore，但1Mb以上的唯一项是_ah_SESSION实体中的_values blob。
控制台的图像位于：http://goo.gl/qP7v7U
我不知道如何解决这个问题，即使以前有人问过这个错误，我的问题是我没有使用文件，实际上我使用的是数据存储。
编辑：再次测试，它似乎在删除操作中中断。这是日志。

新编辑：
我在memcache中发现了一个大字符串，带有_ahs*键，它应该是一个会话变量。我认为这就是变量变得太大的原因。该文本包括一份用于"调试"的HTML副本和一系列产品的版权免责声明。

使用@BalusC "poor man's debugging" approach for Listen and debug JSF lifecycle phases，我发现了END PHASE RENDER_RESPONSE 6之后的错误。
仍然不知道是什么让我的应用程序将这些文件写入存储器。
非常感谢您的帮助。
1MB限制适用于所有数据存储实体。你需要把你的大实体分解成更小的部分。
请注意，会话由Memcache和Datastore备份，并且它们对单个实体都有1MB的限制。请确保您在会话中放置的所有实体都远低于此限制。
