[user12031]

Position:

grpc-go/internal/transport/client_stream.go

Line 74 in d7b3f93

s.ct.closeStream(s, err, rst, rstCode, status.Convert(err), nil, false)

How to reproduce:
1.Adding time.Sleep(time.Second * 7) at the beginning of the method

grpc-go/internal/transport/controlbuf.go

Line 360 in d7b3f93

func (c *controlBuffer) executeAndPut(f func() bool, it cbItem) (bool, error) {

2.Running the test function

grpc-go/internal/transport/keepalive_test.go

Line 392 in d7b3f93

func (s) TestKeepaliveClientStaysHealthyWithResponsiveServer(t *testing.T) {
