Hi Guys!!
I’m sorry for this huge (!!|) delay but I was in vacation and when I came back
I had to manage some trouble situations.
So, this morning I test the latest 2.3 OVS version (commit
5eba2795fc5d4e833e9827ce18f6167e382bf0e1). OS Ubuntu 12.04.4 with Linux Kernel
3.13.0-32 provided by Canonical. Changelog below
http://changelogs.ubuntu.com/changelogs/pool/main/l/linux-lts-trusty/linux-lts-trusty_3.13.0-32.57~precise1/changelog
Unfortunately I have the same issue.

If you are experiencing this problem, can you please test with the
latest master code? It has a fix for one problem and additional
logging in case there are others.

Hi Jesse
I want to know is there any conclusion or what is your next plan ?
Thanks for the additional information.
I'm still having a hard time seeing how a flow could be invalid without
generating any log messages so I just sent out a patch to hopefully cover the
remaining cases (CC'ed to you). The patch is against
master - is it possible for you to try it and report any messages that show up
in dmesg?
Also, can you send a copy of what both your kernel and userspace flow tables
look like when this happens (ovs-dpctl dump-flows and ovs-ofctl dump-flows <BR>
respectively)?
