When a real server goes down ( I forced reboot), ldirectord does not
remove the entry from ipvsadm table. As a result a reconnection to the
common IP from the same client fails. It tries to go to the same client.
I am using roundrobin. I expect ldirectord to remove an entry as soon as
it loses the http link. From then on any new connection should use the
remaining real servers.
This is a shot of my ipvsadm watch ...
