the server's error is as follows: caught by NamedPipeServer.Error event.
System.InvalidOperationException: The pipe is in a disconnected state!

and the client error is:
Grpc.Core.RpcException: Status(StatusCode="Unavailable", Detail="failed to connect to all addresses")
在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)

I have not encoutered this issue in 2.1. After updating to 3.0, it occured once time. I will go with more test.

This exception occurred only in the virtual machine environment. When tested on physical hardware, the program ran continuously for over 5 days without any issues. While there are several differences between these two environments beyond the virtual/physical distinction, this issue has never been reported in any customer environment. Given these observations, I believe this exception is environment-specific.
