I had configured 3 real servers(TUN): RS1,RS2,RS3,IP address of them are 
:RIP1,RIP2,RIP3,one day I remove RS2,RS3 from real server list,when run ipvsadm 
can see following:

[root@cnt ~]# ipvsadm
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP VIP:http rr
-> RIP1:http Tunnel 1 6 3827 

How ever I found some request to VIP is still redirected to RS2,RS3(I have 
cleard real server RS2,RS3 for 1 week already)

run: ipvsadm -Lc:
TCP 00:10 SYN_RECV 59.35.86.90:2507 VIP:http RIP2:http
TCP 00:11 ESTABLISHED 219.148.187.151:14183 VIP:http RIP3:http

When I stop http of RS2 or RS3,some http request to VIP will failure.

Does any one have encountered this problem?
