Did anyone encountered this as well? When sandbox is refreshed, the media contents in salesforce CMS are corrupted. However when we try to delete it, we are seeing this error. Is there any way to fix this?
From the error message, ORA-01403 code refers to "No data found". Also the ID of entity specified in error is the starting with 05T which is ContentBody as per http://www.fishofprey.com/2011/09/obscure-salesforce-object-key-prefixes.html
As confirmed in the comments section, this entity is not accessible as there seem to be dangling references causing the deletion to fail.
The solution would be to log a Salesforce Support case to have these dangling references fixed.
