- Can you give us the ouptput of an ipvsadm -ln to check that you effectively have both weight > 0 (and is 1 realserver located o the same host as the director ?) - Are you proceeding the tests from different clients from different networks ? There is server affinity in ipvs to "stick" client to servers. In the same vein, can you check that there is efectively NO traffic to the second resolver.
