In the first session (frames 28-37), it's the loadbalancer 
(10.132.32.124), that started the teardown of the TCP 
session at frame #33.

But in the second session (frames 51-59,71), it's the upgraded 
webserver (10.132.32.97) that started the teardown of 
the TCP session at frame #56.   Frame #57 is where the client 
(the loadbalancer) attempts the session teardown request 
that is similar to frame #33 of your first session.

The question is why does the new server attempt to tear 
down the session when the old server didn't.

I hope this helps,

Jim Young
