I wanted to upgrade bird on router A from 1.6 to 2.14. As soon as
new bird started up on A, almost all of B, C, etc. started
crashing. Today I started to look into this. I found out I messed
up the configuration on router A, I didn't filter out all routes
from BGP and all those prefixes (IPv4 only, ~100k) were exported
to OSPF. The bird on router A handled it quite OK, but routers B,
C, etc. segfaulted after few seconds of exporting all those
prefixes to kernel. And that happened repeatedly after bird
started again. And again..
<br>
<br>
In bird's log file I found nothing. In system log were 2 lines for
each segfault:

I will try again to upgrade router A without all those prefixes
exported to OSPF, that should work I believe.
<br>
<br>
I am not good at this, but maybe someone could use this
information to find a bug somewhere in bird. Maybe I can help and
try something with the same failing setup?
