 If you can't use the latest kernel 2.6.19-1 then you have to scrap the 
solution.Is the number of connections (active and inactive) constant after 
several minutes? I tested LVS + TUN with 60000 SYN packets per 
second  from 16 000 000 different IP addresses to drain director's 
memory and it seemed to be freeing memory correctly on a 2.6.18-3 
kernel.
 
Yes, after the timeout value (tcpfin) is the number of connections 
constant. ip_vs_conn in /proc/slabinfo is also constant after a short 
time. Unfortunately I can not use 2.6.18. Because I need to use SLES :-( 
 
You are right. Thank you for the truth! But it didn't helps me really.
I have these conditions and I can't change it at the moment. But I work 
on it ;-)
