I've attached the packet dump of the netflow message from the switch

disregard those errors and keep sending netflow messages?
Can you also send the flow expiration messages from the 3 switches
like you did in your first email? It's hard to tell if there is a
problem without something to compare it to.
And please send the log file as well (/var/log/ovs-vswitchd.log) for the
run of NetFlow + expiration messages.

The crux is the netflow message is matching the flow expiration. There
was nothing in the ovs-vswitchd.log file other than messages about
connecting to NOX and exiting fail-open mode, which was well before this
test was performed.
