This patch seemed to work but exposed another bizarre problem. So my
setup is the same, 2 Xen servers with OVS, 1 reference OF software
switch inbetween the two, a wget from .12 to .13 which is running
apache. When the flows expire, dpid 17 which is the OVS on the
physical machine running apache returns a flow expiration that is
~10MB less than the other two flows, but the packet count is 164k
less.. I've attached the logs, it is reproducible on my end.
I've been trying to reproduce this but so far haven't been able to. It
would be great if you can give me some more information so that I can
narrow down my search:
1. If you query the flow stats before the expiration message, do you get
the right results? You mentioned that this was true before but these
flows are less than your 10 second polling interval.
2. Does the problem also occur if you use wildcarded rules instead of
exact match?
3. When do you insert the flows? Before any packets are sent? In
response to a packet in?
4. Are the actions for the rules specific ports or OFPP_NORMAL?
5. Do you see similar results with NetFlow? You can use Wireshark as a
simple NetFlow collector if you don't have one - just tell it to decode
the traffic as cflow.
Any information that you can get will help.
Thanks,
Jesse
