Oh yes, you hold the silver! Please send us the corefile and binary (off-list), we need to know what triggered this in which order. (Yes, multithreading shenanigans, crazy stuff.) If it's too big, ask for an upload link. Thanks! Maria On 18 December 2024 16:12:56 CET, Job Snijders via Bird-users <bird-users@network.cz> wrote:

Second bug? :-)

seems to trigger when peers connect

config:

router id 10.10.255.254; protocol device { } protocol direct { disabled; } protocol kernel { ipv4 { import none; export none; }; }

log stderr all; protocol bgp everything { local as 1000; neighbor range 10.0.0.0/8 external; connect delay time 1; ipv4 {import all; export all; next hop self; import table on;}; }
