Indeed I'm not even sure that it has anything to do with the vr driver -- that's just the only potential symptom that I could find. I've stripped down those boxes so they really don't do anything more than routing (from vr interfaces) and firewall (with pf). The only daemons running (other than getty and sshd) are ntpd and radvd. > Could you show me full dmesg and ifconfig output? It would also be interesting to know whether vr(4) spewed some logs.

I now disabled OpenVPN (it was idle already), an unnecessary VLAN and made the configuration as simple as it can be and still work -- I am including it in full (with un-obfuscated IP addresses to make sure I don't hide any potential problem). > > Some years ago I recall trouble running carp on vlan interfaces.
