What did you do?

Created client Console that send audio samples each N ms using IClientStreamWriter Google.Protobuf Version=“3.13.0” Grpc.Net.Client Version=“2.32.0” Grpc.Tools Version=“2.32.0”

IClientStreamWriter<AudioSample> writeStream = client.SendAudio(metadata).RequestStream;
var audioSampleSource = new AudioSampleSource(commandLineOptions.AudioFilePath);
audioSampleSource.AudioSampleCreated += async (_, audioSample) => await writeStream.WriteAsync(audioSample);

Created grpc server in asp.net core that receives those samples through grpc Grpc.AspNetCore Version=“2.33.1”

SendAudio(IAsyncStreamReader<AudioSample> requestStream, ServerCallContext context)
try 
{
 while (await requestStream.MoveNext(_cancellationTokenSource.Token))
                    AudioSample sample = requestStream.Current;
}
catch (Exception ex)
{ 
}

What did you expect to see?

Forced closing client, server should’ve caught that exception

What did you see instead?

Server crashed, Stack overflow, this happens randomly, from 10 times server client startups, one client closing will cause Stack overflow.

Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).

No. I looked at the method and I didn’t see anything that could cause it.

Will close this one until i can reproduce it at some point
