Hi, We've upgraded recently to 1.6.3 (We were using 1.2.5, which we had running for like 8 years!) and after the upgraded we are seeing a weird behavior. When running ip monitor route in the machine, looks like bird is constantly removing and adding routes, which could be considered normal, but the thing is that it deletes a route and then adds the same route again (Those routes are received via BGP): Heres an example: 103.72.2.0/24 via 91.126.95.153 dev vlan111 proto bird Deleted 103.72.1.0/24 via 91.126.95.153 dev vlan111 proto bird 103.72.1.0/24 via 91.126.95.153 dev vlan111 proto bird Deleted 177.75.72.0/24 via 91.126.95.153 dev vlan111 proto bird 177.75.72.0/24 via 91.126.95.153 dev vlan111 proto bird Deleted 185.165.122.0/24 via 91.126.95.153 dev vlan111 proto bird 185.165.122.0/24 via 91.126.95.153 dev vlan111 proto bird Deleted 196.46.242.0/24 via 91.126.95.153 dev vlan111 proto bird 196.46.242.0/24 via 91.126.95.153 dev vlan111 proto bird Deleted 64.70.30.0/24 via 91.126.95.153 dev vlan111 proto bird 64.70.30.0/24 via 212.80.191.185 dev vlan2 proto bird At the same time we are seeing the following messages on bird log: May 8 13:56:39 icewall-01 bird: Kernel dropped some netlink messages, will resync on next scan. May 8 13:57:02 icewall-01 bird: Kernel dropped some netlink messages, will resync on next scan. May 8 13:57:27 icewall-01 bird: Kernel dropped some netlink messages, will resync on next scan. May 8 13:57:32 icewall-01 bird: Kernel dropped some netlink messages, will resync on next scan. May 8 13:57:59 icewall-01 bird: Kernel dropped some netlink messages, will resync on next scan. Any ideas why this might be happening? Thanks! Saludos Cordiales, Xavier Trilla P.
