FD leak on linux after restart about endless HOT 1 CLOSED

After reading your question I had the same concern about FD leak after restart, so I tested it as follows:

func main() {
	gin.DisableConsoleColor()
	f, _ := os.Create("gin.log")
	gin.DefaultWriter = io.MultiWriter(f)
	router := gin.Default()

	router.GET("/geek", func(c *gin.Context) {
		c.JSON(http.StatusOK, "hello geekfghuang")
	})
	endless.ListenAndServe(":8080", router)
}

Before kill -SIGHUP 886:
localhost:~ $ lsof | grep gin.log
demo 886 geekfghuang 3u REG 1,2 172 1867443 gin.log
tail 896 geekfghuang 3r REG 1,2 172 1867443 gin.log

After kill -SIGHUP 886:
localhost:~ $ lsof | grep gin.log
tail 896 geekfghuang 3r REG 1,2 602 1867443 gin.log
demo 927 geekfghuang 4u REG 1,2 602 1867443 gin.log

So, everything is ok!
