Hi David.
I think that the checks you do do not properly reflect your real distribution
of the trafic.

This just lists current number of running httpd processes.

This just shows number of active and inactive connections on the diffrent
servers. Perhapps, IMHO, the local node can process its incoming connections
faster the the direct routed nodes?

I would try with ipvsadm -L --stats and/or ipvsadm -L --rate
to see the actual distributions of connections.
Hope that this will show you a more even distribution.
