Yes.
The problem here is that persistance still takes effect even
after the real server is removed (I assume you have quiescent=1).
You can change this behaviour by running.
echo 1 > /proc/sys/net/ipv4/vs/expire_quiescent_template
The effect of this is that the persitstance templates
are expired when a connection is made quiescent. And
thus no additional connections will be directed to
the real server in question.
