Hi. Your error code is "File exists" and it's a debug level message. The error means that the same flow is already installed in the datapath. This is a normal condition in OVS since flow installation is happening asynchronously to the traffic and more packets that match the same pattern can arrive while the flow is still not installed. The packets should be processes just fine with the 'execute' datapath call, but the subsequent 'flow put' would fail since we already just installed the flow for a previous packet. So, it is very unlikely to be a cause of your issue. Best regards, Ilya Maximets. _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
