Tang,
You probably need to configure the tcp timeouts for LVS in the kernel:
To list the current timeouts:
root@lb1:~# ipvsadm -l --timeout
Timeout (tcp tcpfin udp): 900 120 300
To set different ones (in seconds):
ipvsadm --set 3600 120 300
To persist this over re-boots put the command in rc.local or somewhere
that runs at boot.
You can't set it to be forever (because that would cause a lot of
issues), most protocols have a keepalive to get around the timeout.
Timeout only counts down when you have idle connections.
