In my case, the server is acting as a backup for 2 carp devices and also
as a master for 2 other carp devices.
But indeed, it is always the same node (part of a 2 nodes setup) that is
crashing. This node just crached again a few minutes ago. It seems
upgrading it to 5.9 makes the bug more frequent. So I am keeping the
other node with «OpenBSD 5.8-current (GENERIC.MP) #1661: Tue Nov 24
20:16:36 MST 2015» for now.
Here is frech output:
