--- Comment #10 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> ---
(In reply to Borja Marcos from comment #9)
> Is thread usage one of the differences between your Bird versions? Or som=
e thread usage pattern?

The BIRD daemon from the port net/bird2 is still single-threaded. BIRD 3, w=
hich
is currently in the early ALHPA stage will be multi-threaded, but we don't =
have
it in the ports tree.

Moreover, I am not able to reproduce the original problem reported here.
Running 4 full view sessions 2x(IP+IPv6) on BIRD 2.15.1 after 1,5 months of
system and session uptime I see no memory leaks=20
