That's only thing I've got... Sometimes it works 4-5 months without problem, sometimes it crashes twice a day :/ Bird running as a ospf DR in nbma mode on 4 vlan's system: Debian 6.0 with custom kernel (3.1.1)

Broadcast address it's now fixed, but it shouldn't segfault bird. Help :(

In Debian 6.0, there is an pretty old version of BIRD. You should try the current one: ftp://bird.network.cz/pub/bird/debian/dists/squeeze/main/binary-amd64/net/bird_1.3.4-1~bpo60+1_amd64.deb I remember that we fixed some problems in NBMA. If the problem would be still here, you could install this package: ftp://bird.network.cz/pub/bird/debian/dists/squeeze/main/binary-amd64/debug/bird-dbg_1.3.4-1~bpo60+1_amd64.deb run BIRD with enabled core dumps and send me the core dump after the crash. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
