After a failed Datapump job, a process can be left alive and not cleaned up. Subsequent attempts to export fail with the following errors:

ORA-31626: job does not exist
ORA-31637: cannot create job SYS_EXPORT_TABLE_01 for user SYS
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT_INT", line 798
ORA-31635: unable to establish job resource synchronization

Cleaning up the abandoned process using the following Note fails:

<Note 453338.1> : Errors ORA-31635 ORA-31637 ORA-6512 With DataPump Export (EXPDP)

Because attempts to identify the serial# of the abandoned process shows that the serial# keeps changing, and is changing too quickly to be able to identify it and kill it before it changes again.
