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

Can you try turning off segmentation offload on the VM running
Apache? Something like:
ethtool -K eth0 tso off gso off
That fixed it.. is this something that needs to be done on every VM or
something that can be fixed in OVS?
I'm going to fix the stats of segmented packets in OVS so that TSO
doesn't need to be disabled.
I also noticed that one of your other flows is off by the size of a TCP
SYN packet. When you respond to a packet in do you send a packet out
plus a flow mod or is it a flow mod with a buffer ID? If you send a
separate packet out then that packet is not counted as part of any flow.
Thanks for all your help in tracing down these issues.
Jesse
