Sorry for the delay in this response... been out for the past few days.
stopping iptables is how I removed it.
>What _EXACT_ test conduct do you run?
ab -n 50000 -c 1000 http://67.72.106.71/
> What are the ipvsadm -L -n and the stats numbers?
with iptables enabled on the LB:
[root@loadb1 ~]# ipvsadm -Ln
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 67.72.106.71:80 wlc
-> 67.72.106.68:80 Route 5 3493 93
-> 67.72.106.66:80 Route 5 3483 96
Active connections with the LB enabled seem to "hang around" more and take much
longer to become inactive.
With iptables disabled and the same ab test the active connections match my ab
connurency. Meaning connections are being made inactive once they are passed
along.
[root@loadb1 ~]# ipvsadm -Ln
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 67.72.106.71:80 wlc
-> 67.72.106.68:80 Route 5 524 12137
-> 67.72.106.66:80 Route 5 456 14222

No message on the LB when this happens.
