CPU1 on ROJ experienced an error last night which caused the system to record a crash dump and reboot. I opened a support case with Sun, and this is apparently a problem with the UltraSPARC II chip that is acceptable if it happens once, but further occurrences would warrant a replacement of the CPU.

Sun has recorded this case in their Best Practices Database; the case number is 64806912. They have system logs for reference, indicating the affected CPU. If this happens again, we should reference this case number so that support can determine whether a CPU replacement is necessary.
