All files in Cloud FTPmoved to Failed folder.

My client has 40 documents in their FTP base location (not in an FTP location created and connected to an in-box.) that randomly move to the Failed folder and rename with an underscore and variable characters.  I can not figure out what is causing this.   What is touching these that the system is Failing them out?
