Failed to determine whether to delete an archived file following the deletion of its placeholder

Hi all,

I'm running EV 9.0.3. I'm getting Event ID 20545 very often (Failed to determine whether to delete an archived file following the deletion of its placeholder. The archived item will not be deleted.). As I have seen there's no a clear solution for this in the Symantec web page. Anyone having this problem? Any ideas or suggestions? The problem is that I think that I have a lot of archive files without the corresponding placeholder using too much space I cannot remove. Is there any way lo locate and remove them?

Thanks in advanced.
