Purge Concurrent Request FNDCPPUR program deletes files from database but not from the file system

Purge Concurrent Request and/or Manager Data (FNDCPPUR) program completes and it deletes concurrent request information from database but relevant files are not removed from the operating system (OS) file system. Concurrent request Log file shows file deletion failed as below.
For example
..
..
* 545345 - /../../w545345.mgr
* 545346 - /../../w545346.mgr

* denotes file deletion failed.

Cause:
The cause of this problem has been identified in Bug 6451570. It is caused by the domain name entry. The system manager_node entry contains the domain also. Therefore comparison between manager_node and node_name fails causing the files not to delete from OS (Unix,Windows,..) file system.
