GRPC error when calling DurableClientContext.getClient

Hi,

I'm experimenting with writing a Java Durable function and have been getting this strange error message when I try and kick off an orchestration using DurableClientContext.getClient.

The issue is transient.
I'm using Java 17.
All the durable function packages are up to date.
The error occurs running locally on windows as-well as on an Azure Function app in the cloud (linux).

The weird thing is the orchestrations all seem to run so I'd like to know if this is safe to ignore.

The error message looks like this:
[2024-02-20T07:21:36.332Z] Feb 20, 2024 6:21:36 PM io.grpc.internal.ManagedChannelOrphanWrapper$ManagedChannelReference cleanQueue [2024-02-20T07:21:36.333Z] SEVERE: *~*~*~ Previous channel ManagedChannelImpl{logId=157, target=localhost:4001} was not shutdown properly!!! ~*~*~* [2024-02-20T07:21:36.333Z] Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

and it stems from this call where I am about to kick-off a new orchestration.

Is it safe to ignore? Should it be logged out?

Thanks,

com.microsoft.durabletask.azurefunctions.DurableClientContext.getClient から始め、DurableTaskGrpcClientBuilder を介して com.microsoft.durabletask.DurableTaskGrpcClient を構築する仕組みを追跡します。ManagedChannel の一時的な警告をローカルで再現し、クライアントのライフサイクルを gRPC のシャットダウンに関するガイダンスと比較します。完了条件は、チャネルが不適切に開いたままになっているかどうか、および警告を防止すべきか、別の方法でログに記録すべきかを判断することです。
