When running a select from a 'X$' table, you could see the error:

SQL> select * from x$kmgsop;
select * from x$kmgsop
ERROR at line 1:
ORA-00600: internal error code, arguments: [17003], [0x57261694], [0], [1], [],

Sometimes, you may also see ORA-00600[kglLock-bad-byd].

This 'X$' table is actually a synonym to a customized view. i.e.

create view X_$KMGSOP as select * from sys.x$kmgsop;

create public synonym x$kmgsop for sys.x_$kmgsop;


The database was upgraded to 12.1 after the view was created.
