Indeed.

I'm facing the same problem here:

gw05.pad.ffho.net:~# dmesg -T | grep bird
[Tue Sep 27 06:53:06 2016] bird[14102]: segfault at 0 ip (null) sp 00007ffd855c52d8 error 14 in libnss_files-2.13.so[ 7f0ac813e000+b000]
[Tue Sep 27 06:53:12 2016] bird6[14133]: segfault at 0 ip (null) sp 00007fffe5a85f98 error 14 in libnss_files-2.13.so [7f50f6dce000+b000]

We are using a PIPE protocol as well, handling 560 routes.

I can provide you with the config as well, if needed.
