I have an environment that displays similar symptoms and unfortunately the in-kernel fix does not help here. I'm currently in the process of debugging and as you point out, debugging issues with the in-kernel datapath or OVS's conversation with it is pretty hard. In reference to the above stated plans to add more logging to OVS in this area I wondered if this work has started. If not I might try to get that done to help resolve the issue we see here, any pointers, in-flight thoughts or work on how to approach it would be appreciated. -- Frode Nordahl > > Best regards, Ilya Maximets. > _______________________________________________ > discuss mailing list > disc...@openvswitch.org > https://mail.openvswitch.org/mailman/listinfo/ovs-discuss _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
