ErrorCode <errca0017>：SubStatus <es0002> Azure缓存服务</es0002> </errca0017>

Question

我在我们的Web应用程序中使用Azure托管缓存服务。我们将一些对象存储在缓存中以及会话中。我们以前没有使用缓存服务来存储会话状态以外的任何内容。前几天我将缓存从基本产品升级到标准产品，并开始缓存一些对象。现在我看到有关缓存的这些错误：

  

ErrorCode：SubStatus：暂时失败。请稍后重试

这些错误的堆栈跟踪是

我想知道这些是否已经开始由于我们为我们的对象实现缓存而在我们仅使用服务进行会话状态之前。以下是我的缓存类。

public static class AzureCacheHelper

非常感谢任何帮助。感谢
