Maybe 5.7 stable? This issue is having really bad impact on my network. Both ISP links are up and running, but - as bgpd dies - my firewall has no routes which effectively stops the traffic flow with the Internet. I have contacted ISPs and ask them to check if they are sending us bad bgp packets. Regardless of that, I think bgpd shouldn't just shutdown itself no matter what payload it gets? Any help with this would be highly appreciated. -- Marko Cupać https://www.mimar.rs
