I'm seeing something very strange here.

Linux Client, RHEL 5.5 LVS Director, CentOS 5.5 Realserver. No Xen in  
this mix.

I'm seeing very strange behavior when a Realserver retransmits a  
packet for which the client has already sent an ACK. The client sends  
a duplicate ack, and here's where the weirdness happens--the duplicate  
ack bounces back and forth between the LVS director and the realserver  
until the TTL goes to zero and the client receives a TTL exceeded ICMP  
message.

Has anyone seen this behavior before? LVS-DR, by the way.
