A common thread through the database bugs listed above is that the problem does not occur if bind peeking is shut off. Temporarily disabling bind peeking allows you to confirm whether this is the case in your environment as well.
This can be done dynamically:
SQL> alter system set "_optim_peek_user_binds"=false;If the ORA-3137 [12333] error no longer reproduces after disabling bind peeking, then in most cases, the problem is due to one of the database bugs listed above, or due to some variant of one of those bugs.
