good, so your network must be configured correctly.

I don't know anything about your app. Is it a single port service?
Use netstat -an on the realserver when the java client is connected
to it directly, not through the director, to look for the connections
from/to the client.
Are there transitory call backs from the realserver?
You can test this by changing to LVS-NAT and nat'ing all
clients on the realservers. rsh as service fails on LVS-DR for this reason
but works for LVS-NAT.
ALternately you could handle this by providing a route
client<->RIP.

I assume the client is hung at this stage?
