It's hard to tell for sure what is going on here, but the issue might be caused by a kernel issue fixed in: https://lore.kernel.org/netdev/167111551443.359845.7122827280135116424.stgit@ebuild/ You may need to upgrade your kernel, if it doesn't include the commit above. > Datapath Flow : > > > recirc_id(0),in_port(3),ct_state(-new-est-rel-rpl-inv-trk),ct_label(0/0x1),eth(src=5c:e7:47:05:34:00,dst=fa:16:3e:25:b1:3b),eth_type(0x8100),vlan(vid=80,pcp=0),encap(eth_type(0x0800), > > ipv4(src=172.16.0.0/255.252.0.0,dst=172.30.48.48,proto=6,ttl=63,frag=no)), > packets:2355652448, bytes:11500879337271, used:0.220s, flags:SFPR., > actions:ct_clear,ct_clear,set(eth(src=fa:16:3e:8f:73:57,dst=fa:16:3e:59:e8:49)),set(ipv4(dst=10.147.7.12,ttl=62)),pop_vlan,ct(zone=1),recirc(0x13b6c8) > > ovs version: 2.15.2 Note: 2.15 is a fairly old release now and it is no longer supported. You should upgrade to at least 2.17.
