ORA-46268: Conflicting operation on audit table(s)

Solution: 

Close the offending session, establish a new session, then try again.

Steps to reproduce.

1. Ran dbms_audit_mgmt.init_cleanup through SQL Developer. 
2. Control+C out of statement. 
3. Attempt to run init_cleanup again.

No amount of waiting got around the error. 

There was clearly nothing running.
Re-connected to the database, ran without issue.

Full error: 

Error report -
ORA-46268: Conflicting operation on audit table(s)
ORA-06512: at "SYS.DBMS_AUDIT_MGMT", line 61
ORA-06512: at "SYS.DBMS_AUDIT_MGMT", line 774
ORA-06512: at line 2
46268. 00000 -  "Conflicting operation on audit table(s)"
*Cause:    Audit tables were being operated by more than one DBMS_AUDIT_MGMT
           API from different sessions. The simultaneous execution of the
           following API with one another and with itself can cause the
           conflict: INIT_CLEANUP, DEINIT_CLEANUP, SET_AUDIT_TRAIL_LOCATION
           and MOVE_DBAUDIT_TABLES.
*Action:   Wait until the execution of one of the API's completes and try
           executing the API again.

Could not find anything on MOS (or any English forums/blogs) about this error outside of the below description.

Related note: 

The init cleanup also moves the audit log from system to sysaux - unless you specify a different tablespace using set_audit_trail_location.
