### What did you do?

I initially observed these errors in Unix domain socket connection between daprd and its pluggable component. After modifying the RouteChat code in grpc-go/examples/route_guide, I was able to reproduce them. 
The issue is reproducible on other machines as well, and it occurs consistently across different versions like go1.19 and go1.22. Additionally, it persists on Windows 11.

## What I did

The changes to server.go and client.go can be found at [this repository](https://github.com/dizecto/grpc-go-uds-test).

### Use Unix domain socket
```
    // server.go
    os.Remove("D://temp/test.sock")
    lis, err := net.Listen("unix", "D://temp/test.sock")

    // client.go
    serverAddr = flag.String("addr", "unix:///temp/test.sock", "The server address in the format of host:port")
```

### Include a dummy string in the Message for sizing purposes
```
    // client.go
    {Location: &pb.Point{Latitude: 0, Longitude: 1}, Message: "First message: 1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890"}
```

### Continuously send requests without concurrency and log status
```
    // client.go
    for {
        for _, note := range notes {
            if err := stream.Send(note); err != nil {
                log.Fatalf("client.RouteChat: stream.Send(%v) failed: %v, outstanding: %d", note, err, outstanding)
            }

            atomic.AddInt64(&sent, 1)
            // current := atomic.AddInt64(&outstanding, 1)
            atomic.AddInt64(&outstanding, 1)
            if true {
                if sent%10000 == 1 {
                    log.Printf("client.RouteChat: a lot of outstandings:  %4d, sent: %d, recv: %d", outstanding, sent, recv)
                }
                // time.Sleep(time.Microsecond)
                if sent%10000 == 1 {
                    log.Printf("client.RouteChat: decreased outstandings: %4d, sent: %d, recv: %d", outstanding, sent, recv)
                }
            }

            //<-recvc
        }
    }

```

### Respond to received requests as they are
```
// server.go
func (s *routeGuideServer) RouteChat(stream pb.RouteGuide_RouteChatServer) error {
    for {
        in, err := stream.Recv()
        if err == io.EOF {
            return nil
        }
        if err != nil {
            return err
        }
        if err := stream.Send(in); err != nil {
            return err
        }
    }
}
```

## How to reproduce

### Install go and set up environment variables
1. Install go1.21..windows-amd64.msi
2. Set the following environment variables.
```
GRPC_GO_LOG_SEVERITY_LEVEL: info
GRPC_GO_LOG_VERBOSITY_LEVEL: 99
```

And if 'GODEBUG: http2debug=2' is present, delete it. When printing this debug log, no errors were observed to occur.

### Clone the repositories and compile for Unix domain socket
```
> mkdir github.com
> cd github.com
github.com> git clone --depth 1 --branch v1.62.1 https://github.com/grpc/grpc-go.git
github.com> git clone https://github.com/dizecto/grpc-go-uds-test.git
github.com> copy /Y .\grpc-go-uds-test\route_guide\unix\client\client.go .\grpc-go\examples\route_guide\client\client.go
github.com> copy /Y .\grpc-go-uds-test\route_guide\unix\server\server.go .\grpc-go\examples\route_guide\server\server.go
github.com> cd grpc-go\exmaples
github.com\grpc-go\exmaples> go mod vendor
github.com\grpc-go\exmaples> go build -mod vendor route_guide\server\server.go
github.com\grpc-go\exmaples> go build -mod vendor route_guide\client\client.go
```

### Execute 'server.exe' and 'client.exe' in separate command windows.
1. Create a "temp" directory in the D drive
```
github.com\grpc-go\exmaples> mkdir D:\temp
```
2. Launch 'server.exe'
```
github.com\grpc-go\exmaples> server.exe
2024/03/14 10:13:40 INFO: [core] [Server #1] Server created
2024/03/14 10:13:41 INFO: [core] [Server #1 ListenSocket #2] ListenSocket created

```
3. Launch 'client.exe'
```
github.com\grpc-go\exmaples> client.exe
2024/03/14 10:14:28 INFO: [core] [Channel #1] Channel created
2024/03/14 10:14:28 INFO: [core] [Channel #1] original dial target is: "unix:///temp/test.sock"

```
4. Wait for errors

Be prepared to wait for errors; they may occur after several minutes or even tens of minutes.

### What did you see happen?

## Try 1

### What did you expect to see?

Continue running as if using a TCP socket connection.

When using TCP connection, there are no code differences besides the address specified in 'server.go' and 'client.go'. They can be found at [this repository](https://github.com/dizecto/grpc-go-uds-test.git).
