[SunHELP] Advice requested on UltraSPARC-III reboot problem

[Kent Fitch]

Hi,

We have a UltraSPARC III single CPU 750Mhz, 1GB machine which has
rebooted itself 3 times in the past 4 months.  We've applied the
latest patch set recommended by Sun.  Yesterday it rebooted
again, and for the first time generated some messages immediately
before rebooting.  Our local Sun people think they do not contain
enough information to diagnose the problem, so I'm looking for
references to information which can help me understand going on.

Here are the messages written just before the reboot:

The file systems were then synced at the machine rebooted.

Any pointers are welcome.
