>Description:
When adding new pseudo-interface, like tap, openbgp will exit. In syslog i see following reports from bgpd:

Nov 26 12:17:44 xxxxxx bgpd[1755]: kernel routing table decoupled
Nov 26 12:17:44 xxxxxx bgpd[1759]: neighbor xxx.xxx.xxx.xxx (xxxxxxxxx): state change Established -> Idle, reason: Stop
Nov 26 12:17:44 xxxxxx bgpd[1759]: neighbor xxx.xxx.xxx.xxx (xxxxxxxxx): state change Established -> Idle, reason: Stop
Nov 26 12:17:44 xxxxxx bgpd[1759]: session engine exiting
Nov 26 12:17:44 xxxxxx bgpd[1758]: route decision engine exiting
Nov 26 12:17:44 xxxxxx bgpd[1755]: Terminating

>How-To-Repeat:
Create a new pseudo-interface and configure it, while bgpd is running:

ifconfig tap10 create
ifconfig tap10 inet 192.168.100.1/24 up

Openbgpd will exit.
>Fix:
I don't know how to fix this problem, but on 8.0-BETA2 works fine.
I have the newest openbgpd installed from ports:

# pkg_info -x openbgpd
