Unfortunately, it's realatively impossible to determine what caused the crash, retro-actively:<br />
&nbsp; &nbsp;-without a core file<br />
&nbsp; &nbsp;-error message(s)<br />
&nbsp; &nbsp;-duplicating by performing similar task that was running when crash occured (i.e. backup) <br />
&nbsp; &nbsp;<br />
<br />
Try to determine when the system crashed, using the 'last' command and figure out what the system was doing at that time.<br />
<br />
<br />
Otherwise, make sure you are properly patched, esp. kernel levels.<br />
<br />
Good luck...

We have a SunFire v3800 machine (Solaris 9) recently reboot automatically without any signal, after started up, nothing mentioned in /var/adm/messages, etc log file. <br />
<br />
Nothing done to the OS...<br />
<br />
Anyone has such experience?<br />
Any commands/tools available to enhance the logging?

Auto-reboot without any signal and logging

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
