zapgrpc : Warning http2Server.HandleStreams failed to read frame - when client close #5169
Description
Describe the bug
During the lifetime of my application, everything is working properly.
Once I closed it, I have a "warning" in the collector:
warn zapgrpc/zapgrpc.go:191 [transport] transport: http2Server.HandleStreams failed to read frame: read tcp [::1]:4317->[::1]:64933: wsarecv: Une connexion existante a dû être fermée par l’hôte distant. {"grpc_log": true}
"Une connexion existante a dû être fermée par l’hôte distant." means "an existing connection might have been close by remote host"
Steps to reproduce
Launch the collector with the config below.
Launch a .net console project with in main:
var serviceName = "MDS.TestSerilog.Test";
var serviceVersion = "1.0.0";
// Configure important OpenTelemetry settings and the console exporter
using var tracerProvider = Sdk.CreateTracerProviderBuilder()
.AddSource(serviceName)
.SetResourceBuilder(
ResourceBuilder.CreateDefault()
.AddService(serviceName: serviceName, serviceVersion: serviceVersion))
.AddConsoleExporter()
.AddOtlpExporter(opt =>
{
opt.Endpoint = new Uri("http://localhost:4317");
})
.Build();
var MyActivitySource = new ActivitySource(serviceName);
using var activity = MyActivitySource.StartActivity("SayHello");
activity?.SetTag("foo", 1);
activity?.SetTag("bar", "Hello, World32!");
activity?.SetTag("baz", new int[] { 1, 2, 3 });
What did you expect to see?
As my application is closing properly I shouldn't see any warning on the collector side
What did you see instead?
in the log I'm seeing a warning:
" zapgrpc : Warning http2Server.HandleStreams failed to read frame"
