Hi Jesse,
Certainly the first, however I am seeing this bug on both short and
long (20+seconds) flows, both with an idle timeout of whatever the
default NOX 0.4 timeout is (I'm assuming 5s?). Does that qualify?
Yeah, a 5 second idle timeout will trigger this problem. My guess is
that this patch will fix your problem.

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.
Thanks,
David
