Data fault

Cause

This error is a kind of BAD TRAP that usually causes a system panic. When this message appears after a BAD TRAP message, a system text or data access fault probably occurred. [See the message BAD TRAP for more information.] In the absence of a BAD TRAP message, this message might indicate a user text or data access fault. Data loss is possible, if the problem occurs other than at boot time.

Action

Make sure the machine can reboot, then check the log file /var/adm/messages for hints about what went wrong.
