求助：golang 并发发起TCP连接 导致 accept卡住

测试用例代码如下 并发发起2000个连接会出现 accept卡死的情况 只有drawin和linux系统会有这个问题，windows正常 ```golang func TestStressConn3(t *testing.T) { const max = 2000 var number = 0 l, _ := net.Listen("tcp4", "127.0.0.1:9003") wg := sync.WaitGroup{} wg.Add(max) for i := 0; i < max; i++ { go func() { t.Log("start conn") net.Dial("tcp4", "127.0.0.1:9003") t.Log("end conn") }() } go func() { for { number++ fmt.Println("accept", time.Now().String()) l.Accept() fmt.Println("end", time.Now().String(), number) wg.Done() } }() tm := time.Now() wg.Wait() t.Log("用时", time.Now().Sub(tm).Seconds()) } ```
