Identified process hung message in alert log. The trace file generated when message posted contained following information:

kewrpanp - Clearing the error, continue to next tableDDE: Problem Key 'ORA 12751' was flood controlled (0x2) (no incident)

ORA-12751: cpu time or run time policy violation

*** KEWROCISTMTEXEC - encountered error: (ORA-12751: cpu time or run time policy violation

ORA-06512: at "SYS.DBMS_STATS", line 956

ORA-06512: at "SYS.DBMS_STATS", line 24249

ORA-06512: at line 1

)

There are couple of things i observed while troubleshooting the issue.

1. The execution status for task_name SYS_AUTO_SQL_TUNING_TASK is either INTERRUPTED or EXECUTING.

Howdy, Stranger!
