In ilom/@usr@local@bin@spshexec_show_-script_@X@logs@event@list.out we will see that the OS is panicking:
824 Wed Dec 4 04:36:07 2002 System Log minor
Host: Solaris rebooting
823 Wed Dec 4 04:27:29 2002 System Log minor
Host: Solaris panicking
822 Fri Aug 31 05:37:39 2001 System Log minor
Host: Solaris running
For the above scenarios, we can see that the internal HUB Controller embedded on the MB failed, thus the Motherboard needs to be replaced
