Error: Hold timer expired

[Maria Matejka]

Hello!

You probably hit the architectural limits of single thread routing. Try BIRD 3 (alpha).

Also with this load, it's very much recommended to have a BIRD Support package to have us booked for resolving high load problems. It's a time-consuming and very fiddly job for experienced developers. Please see https://bird.nic.cz/en/commercial-services/ for more details, and/or contact me off-list for a customized quote.

Happy routing!
Maria
