[Linux-HA] Ldirectord and jboss port

We've got an application serving up JBoss on port 8080. I'm using LVS to
load balance and have incorporated ldirecord into LinuxHA to provide a
higly available LVS-tunnel cluster. We found that by starting up Jboss
on the "real" servers and listening on the RIP that for some reason, LVS
cannot seem to communicate with the real servers. However, by starting
up JBoss listening on all interfaces (0.0.0.0) we are able to
successfully direct traffic through the VIP to the real servers in rr form.
I have 2 questions. First, what implications are there with starting up
JBoss listening to all interfaces (which I think is the default btw) as
opposed to listening to the RIP? I can't see why leaving it listening on
all interfaces would pose and issue. Also, does anyone have any ideas
why it doesn't seem to work going to the RIP?
