无法在 Orleans Runtime 中激活 Grains

Question

我在激活谷物时遇到问题。我成功地建立了筒仓，但是grain激活抛出了TaskCanceledException。

以下日志可能有助于理解问题：

[Error] Orleans.Grain: Error activating grain [Activation: S192.168.1.33:10025:58975009/Placement=RandomPlacement State=Activating]
System.Threading.Tasks.TaskCanceledException: Timed out waiting for OnActivateAsync to complete

   at System.Threading.Tasks.ValueTask.ValueTaskSourceAsTask.<>c.<.cctor>b__4_0(Object state)

我的猜测是我的谷物无法与筒仓通信。

尝试过的场景：

1.配置 Host Builder 时，将 Grain 的 ActivationTimeout 更改为 3 分钟（默认为 2 分钟）。

2.检查长时间运行的应用程序的 OnActivateAsync 方法。

请帮忙解决这个问题。

您可以分享一些代码重现来澄清问题吗？这很大程度上表明存在某种异步/等待错误，因为它正在超时。
