Hullo, On my 8.0-RELEASE-p1 system, my ::1 address on lo0 has been magically replaced with a global routable IPv6 address I have configured on lo3. This has happened two times with a week or so interval, without me doing any ifconfigs. With `replaced' I mean that ::1 is simply gone from the interface, although a route to it remains. Instead of ::1, one of the addresses configured on lo3 is also there on lo0. The address that ::1 is suddenly replaced with, is assigned to a jail that has it assigned to a child jail. There are also other IPv6 addresses assigned to this jail and its child jail, but those don't show up on lo0 all of a sudden: only one out of the set does. My question is, has anyone seen anything like this or does anyone have a clue how I could debug this? I cannot easily reboot the affected system to add debugging statements to the kernel, etc, but perhaps there are other ways? Thanks, Pieter
