Multiple ECA Instances Processing Same File And Logging Errors Constantly (Doc ID 2813142.1)

Symptoms

On Oracle Communications Network Charging and Control (NCC), 12.0.2.0.0 version, EDR Agent

After a SLEE restart, it appears that all edrControlAgent instances have picked up the same file incorrectly

As a result, each line fails the input criterion and logs an error. When ECA tries to remove the file from processing to failed/success at the end one of the other instances has already moved it so it gets stuck in a loop processing a non-existent file. This file no longer exists in "processing" directory, but has been moved to the "failed" directory by one of the other instances that incorrectly processed it:

ERROR:
-----------------------

This results in multiple ECA instances writing to ecaProgress.txt, but only one of them is going to succeed and constant logging of these Errors to the syslog.

STEPS
-----------------------
The issue can be reproduced at will with the following steps:

1) SLEE running, multiple ECA instances configured all using same input/processing/success/failed directories
2) Drop multiple input files into input directory
3) Confirm processing in ECA/processing directory
4) Restart SLEE
