I've got a panic:
in /var/log/messages:
...
>Mar 27 02:02:50 ns /kernel: changing root device to wd0s1a
>Mar 27 02:02:50 ns /kernel: WARNING: / was not properly dismounted
>Mar 27 02:02:51 ns savecore: reboot after panic: zone: entry not free
...
Acoording to maiilog, this happened right after daily job
sent output to me:
