ORA-06512: at "SYS.DBMS_AQ_INV", line 1248

Hi

I was getting in the alert log:-

ORA-00600: internal error code, arguments: [13011], [7907], [12679954], [1], [13461738], [0], [], [], [], [], [], []

ORA-01403: no data found

ORA-06512: at "SYS.DBMS_AQ_INV", line 1248

I tried analyze table SYS.SCHEDULER$_EVENT_LOG validate structure cascade;

and got error

ERROR at line 1:

ORA-01499: table/index cross reference failure - see trace file

but when I run analyze table SYS.SCHEDULER$_EVENT_LOG validate structure it was analyzed , suggesting an issue with index?

So I ran

select 'alter index '||owner||'.'||index_name||' rebuild;' from dba_indexes where table_name='SYS.SCHEDULER$_EVENT_LOG';

and got :-
