created by net/http.(*Server).Serve
/root/src/go/src/net/http/server.go:2608 +0x2ce
I'm running the http.Server with ConnState: timeoutIdleConns
func timeoutIdleConns(nc net.Conn, cs http.ConnState) {
switch cs {
case http.StateIdle, http.StateNew:
nc.SetReadDeadline(time.Now().Add(time.Minute))
default:
nc.SetReadDeadline(time.Time{})
}
}
>From what I can tell, this callback is triggered with StateNew, prior to
conn.serve() being created, so the ReadDeadline should be present in the
stalled goroutine calls.
What's going on?
