I'd post this on freebsd-net or an openbgp mailing list (is there
one?)...OpenBSD which develops openbgp has fixed numerous bugs since
OpenBSD 3.7 released, I'd be willing to bet that OpenBSD 3.9 w/
OpenBGP 3.9 (if we consider the version of OpenBGP to be the same as
the OS it was developed on) works "better" (for some definition of
better which may or may not be yours).

Good afternoon,
The issues is dropped neighborships between IBGP peers every 1-2
minutes. One host is a PFsense (FC1) firewall running openbgp package version
3.7_2(not sure what the actual version is) and the other a Fedora Core
5 box running Quagga 0.98.6. The configs and debugs are below, anyone
seen wierdness like this before?
This is not a complex config, looks like an undocumented feature.
Thanks all.
