gobgp like Infinite loop, if dynamic neighbors contain it self.

start first gobgp not use many cpu

I can't reproduce this. Please send the minimum configurations that cause this. For example, this happens without route reflector configuration? how about zebra? What neighbors matter? Please drop all the unrelated configurations.

use zebra of frr 7.1 daemon run with " -A 127.0.0.1 -s 90000000 --log stdout --log-level info -k 60 -r -z /var/run/frr/zserv.api" . without dynamic group anything is ok.
