Public bug reported: OpenStack release - Wallaby OVN version 21.06 OVS version 2.16 CentOS Stream 8, various kernel versions
Seeing a lot of ovs-system: deferred action limit reached, drop recirc action on the active gateway chassis. Also the dropped packets counter for breth2-ovs (which is the external bridge) is increasing over time.

I'm not sure if that's Neutron bug or OVN bug. It's not a blocker, or a huge problem - everything works properly. ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
