What triggered the Error:

A worker process was requested to clean up and exit (signaled by PMON, doing cleanup because the master process died unexpectedly).

What should we do to fix it:

If this error occurs from a Data Pump client (e.g. expdp or impdp), it means that the master process for the operation died unexpectedly. Check the log file for the operaton and the trace file for the master process for any additional information. Try the operation again. If the error occurs again, contact Oracle Customer Support and report the error.
