2 virtual on the same interface

Hi,

We are using the "Streamline High Availability and Load Balancing"
and have created 2 VIP on the eth0 interface. Everything work fine. Client can 
access both real server using the 2 VIP. 

However, there exist a problem on the real server which don't have ldirectord 
start up. 


server1:6083          server2:6083
ldirectord 

Suppose client on a third server is connecting to server2:6083 through one of 
the VIP. netstat on server2 show that 6083 has a ESTABLISHED connection. When 
the client is killed, we expect that the ESTABLISED connection will disappear 
at server2. However, it still exist for over 1 minute before FIN_WAIT can be 
seen. As there are many clients making connection to the VIP, too much of 
established connection will be a problem to us.

This will not happen if we just use 1 VIP on eth0. Any idea why this happen? 
Thanks.

Eric
