Kernel itself usually operate interface routes only.
Addtitionally, it doesn't install routes with flag 1.
Either some other dynamic routing software is running or something
strange is happening with bird6.

Unfortunately I dont't have any bird6 in production because having
bird/ospf3 running is the best and easiest way to cause all quagga ospf3
processes in she same subnet to crash (till 0.99.18 ?)

fredrik, can you try the following:

issue "route -n monitor" on the server with bird6,

run bird6 with kernel protocol debug,

get to the problem situation (you wrote you've got a more or less easy
way to trigger this)

and show us monitor output and bird logs ?
