Within our Test environment, the DAC fails random tasks through both incremental and full loads. When we check the log files, we are receiving the same ORA-12537: TNS:connection closed error. Once we set the status of the task from 'Failed' to 'Queued' and restart the DAC, the task completes successfully. This does not always occur on the same tasks and appears to happen at somewhat random times.
