OSD-04008 implies OS specific issues. The first thing that need to be investigated is the existence of one of the following:

2- Operating system backup software that backs up the database folders. Some customers uses backup software from remote servers to backup all their servers at night. If yes, can you disable it or reconfigure it to exclude Oracle database folders.
