If you're running netstat on the director you won't see them as the
sessions are not established at that level on the director. The session
table seen by ipvsadm is at ip_vs level, not IP - it's application
agnostic.
If you're running netstat on the realserver and it's already gone
through the various WAIT states and timed out, then you're using -DR and
the director isn't seeing the full conversation so doesn't know what's
going on. The sessions seen under "ipvsadm -Lnc" will disappear after (I
think) two minutes, unless you're using persistence at which point it
depends on your configuration.
