I don't understand the problem. I think you have

o an LVS with two VIPs

o two NICs on the realserver(s), and apache
listening to the two VIPs on the realservers.

o requests to either VIP from an outside
client are answered by only one of the
apache demons.

If so, I can't imagine how this could happen.

can you show the output of ipvsadm etc?
