cause :


The errors can be seen on any of the database versions for which we have released a bundle patch ( PSU / SPU / DBDP) in April: Oracle RDBMS 11.2.0.4, Oracle RDBMS 12.1.0.1, Oracle RDBMS 12.1.0.2. 

ug 24316947 - ORA 7445 AND ORA 600 AFTER APPLYING 11204/12101/12102 APR DBPSU/DBBP
 The following bugs have been closed as duplicates of Bug 24316947:

workaround :

A workaround is to disable  NOT EXISTS auditing - run "NOAUDIT NOT EXISTS".  AUDIT NOT EXISTS audits all SQL statements that fail because an object doesn’t exist.
This bug 24316947 fix is included in Database Patch Set Update 2016 patch.
For a permanent solution, apply Patch 24316947 or Database Patch Set Update 2016  patch.
