Public bug reported: Hello,
Opening a bug as per Slawek Kaplonski suggestion on the mailing list (http://lists.openstack.org/pipermail/openstack- discuss/2020-September/017108.html) We are experiencing flow drops when restarting the ovs agent. Symptom example when restarting the agent: http://paste.openstack.org/show/797669/ * We are running neutron 14.0.2 * Neutron configuration: http://paste.openstack.org/show/797646/ * ml2 configuration: http://paste.openstack.org/show/797647/ * openvswitch_agent configuration: all defaults, nothing customized (conf file only contains empty « [DEFAULT] ») * ovs agent debug logs: file attached (wasn't able to paste all of it on paste.openstack.org) Several tests been conducted for different types of flow, east-west, north-south, flat provider-networks, self-service networks, with or without our corporate proxy. In each configuration some flow would cut. If I switch back to firewall_driver=iptables_hybrid in the securitygroup section of ml2 configuration, we do not experience the issue anymore. Let me know if additional information should be provided. As soon as I got some time to deploy a devstack I’ll have a look if the issue can be reproduced using lastest master branch. ** Affects: neutron Importance: Undecided Status: New ** Attachment added: "ovsagent.log" https://bugs.launchpad.net/bugs/1895038/+attachment/5409147/+files/ovsagent.log -- You received this bug notification because you are a member of Yahoo!
