Hi, .*:
I’m not entirely sure if this belongs here or in freebsd-bugs, but since I haven’t found a bug myself, I chose to send it here first. Please let me know if I’m in the wrong place.
I just experienced a kernel panic/reboot and I’m not sure what’s happening. /var/log/messages only provides:
Jul 5 02:19:37 shemuel syslogd: kernel boot file is /boot/kernel/kernel

Jul 5 02:19:37 shemuel kernel: Automatic reboot in 15 seconds - press a key on the console to abort
Jul 5 02:19:37 shemuel kernel: Rebooting…
I do have a dump that I can provide if someone needs it.
This particular box runs two jails and that’s about it. At the time of the panic, I issued "sysctl -a | grep jail” from within one of my jails.
Any help would be greatly appreciated.
Thanks,
Jake
