Hello,
after upgrading to debian buster with kernel 4.19 we also had problems.
How filled is your route cache compared to the sysctl treshold? See the
(hex) value with :
cut -d'' -f 6 /proc/net/rt6_stats
Do you get a "Network is unreachable" error at some point if you do an
"ip route get" on each prefix of your (ipv6) routing table? (while you
are doing this test you should see the cache being filled according to
the rt6_stats file as said before)
How filled is your neighbor table compared to the sysctl treshold? You
can read it with :
ip -6 neigh sh | wc -l
Do you notice random drops on Bird sessions?
