Thanks Herta, I am able to verify that every message is passing through the loadbalancer host using tshark. That was the part of my sentence that got truncated. I have now modified my experiment a little bit : Its turns out that all requests from a particular client keep getting routed to a particular RealServer ( #1 or #2 depending on the run) persistently although I have persistence turned off. I have two clients sending requests to the load balancer /cluster. I tested the scenario when requests from Test Client #1 ( TC#1) got sent via the load balancer to RealServer#1 while all requests from TC#2 went to Real Server #2. ( As soon as I shutdown one of the RealServer service ports say #1, the piranha routing table, promptly excluded the dead real server/ Realserver#1 [ both in the piranha UI as well in the output of /sbin/ipvsadm ] TC#1 to got failures for almost 5 minutes while TC#2 which was being serviced by RealServer#2 continue to go throuh and did not have any failures. Requests from TC#1 took about 5 minutes to start getting routed to RealServer#2. In a subsequent run of the same scenario as above, I restarted pulse to see if that would cause immediate re routing of requests from TC#1 to RealServer#2. But it made no difference, furthermore, on yet another run, I restarted both /etc/network and pulse and that did not make any difference either.

You can easily check whether the packets pass through the load balancer by executing "tcpdump host [client-hostname]" as root on the load balancer. That will print all packets to and from the client.
