ORA-31613: Master process DM00 failed during startup

While taking export backup using data pump user received following error.

ORA-31637: cannot create job SYS_EXPORT_SCHEMA_01 for user
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 1587
ORA-39062: error creating master process DM00
ORA-31613: Master process DM00 failed during startup.

Normally user receives this error when maximum numbers of processes are exceeded. You will see below error in trace files.

ORA-00020: maximum number of processes (150) exceeded

Solution: To fix the issue increase PROCESSES initialization parameter and restart the database.

If you don’t see the error ORA-00020 trace file then look for other error messages which will help to fix the issue. 

I had faced similar issue and  but don't see ORA-00020 error. After looking the other error messages I see that child processes are terminated and in my case restarting the database resolved the issue.
