[nycbug-talk] rtadvd on openbsd talking to mac

[nikolai]

Hi folks,

At home I have a router running OpenBSD-current with three ifs: fxp0, re0,
and re1.
External fxp0 goes to the cable modem with dhclient. re0 goes to a switch
doing dhcpd,
and re1 just has a crossover cable hanging off of it, where I usually
connect my powerbook.
I have an ipv6 tunnel to HE, addresses are assigned to internal
interfaces, so I run rtadvd
on both re0 and re1.
Everything seems to be working but recently I started noticing these
errors on re1:

Mar 12 20:00:17 login rtadvd[27685]: <ra_output> sendmsg on re1: No buffer
space available
Mar 12 20:03:48 login rtadvd[27685]: <ra_output> sendmsg on re1: No buffer

Mar 12 20:08:06 login rtadvd[27685]: <ra_output> sendmsg on re1: No buffer

Mar 12 20:15:44 login rtadvd[27685]: <ra_output> sendmsg on re1: No buffer

Mar 12 20:35:08 login last message repeated 2 times
Mar 12 20:44:47 login rtadvd[27685]: <ra_output> sendmsg on re1: No buffer
space available

This seems to be happening when I don't have that crossover cable plugged
into anything.
Can anybody share any clues on what might be going on and where to dig
further?

Thanks.
