Hi Robert,
thanks for the report.
How did you manage to fix the BGP issue? From what you sent us it should
be working (we use two channels per BGP protocol in our tests as well),
so I am curious.
Would you be able to sent us logs just before the crash, config, core
and exact binary you used? So we have a better idea what we dealing with.
Thanks,
David

Migrating from Bird 2.1.8 to 3.2.1 on FreeBSD 15
Both built from poudriere ... packages and installs fine. Worked
through a MP-BGP next hop issue. BIRD appears to read the config, but
then just aborts and crashes:
