Labview crashes when two (or more) servers are stopped #356

Closed HouetIBS closed 2 months ago

HouetIBS commented 6 months ago

I'm using two servers and two clients in one application. When running the servers and clients, this works really well.

When I close one server (no matter which one I choose), the server is closed nicely as well. But, when I close the second server, Labview crashes when calling the LVStopServer in the dll. image (The gRPCid server is for both servers not 0 and unique for all servers)

If I just use the simple 'helloworld'-example and just copy an extra server in the application, it is really easy to reproduce the problem. image

Would be great if this can be fixed.

Thanks in advance.

PS:

With kind regards,

Erik

Hi @HouetIBS, we wanted to check with you, which NI product team do you belong to ?

Hi,

I do not really understand your question. I work for IBS Precision Engineering in the Netherlands. We use Labview for pretty much every application we build.

The current application, which uses gRPC, is written in Labview 2021 64bit.

I really like the gRPC/proto implementation to use as a communication standard between software products. Good that you all started a gRPC implementation for Labview. Unfortunate, there are some challenges to overtake to make it a really good experience.

Met vriendelijke groeten,

Hi @nischalks,

We are utilizing LV gRPC for a key customer project. We’ve encountered an issue where stopping two parallel-running servers results in a LabVIEW crash. The first server shuts down correctly, but LabVIEW crashes during the closure of the second server, leading to a loss of connection to the RT Target. This issue has also occurred on LabVIEW RT. Are there any updates on the status of this issue? Thank you in advance.

Not sure if you are facing the same issue as this one https://github.com/ni/grpc-labview/issues/279

@SallyTYT thanks for the comment,

My case is little bit different, I could properly get data from both clients, the problem is only when I am Closing the servers, first server closes properly but during second server closure LV crashes and connection to RT target loses.
