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 . 有一天，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，而在我们只使用服务进行会话状态之前 . 以下是我的缓存类 .

});
return obj;
}
catch (Exception e)

logService.InsertLog(LogTypeEnum.Error, "Error in cache get", e);
logService.SaveChanges();
return null;
}
}

_retryPolicy.ExecuteAction(() =>

foreach (var item in items)

});
}
catch (Exception e)

}
对此有任何帮助非常感谢 . 谢谢
