No File Status on Transfer Fail, Does Not Retry

I have set up a recurring, scheduled folder upload to my FTPStream server using SSL Explicit. After a period of time transfer will stop on file, preventing the scheduled upload from continuing.

I have set favorite's properties to enable Force PASV IP mode. Problem still persists.

Only solution I have found is restarting SmartFTP which conflicts with having a recurring, scheduled task.

Version: 4.0.1138.0

Has this bug been replicated yet?

We are unable to reproduce it. Do you have the Max Retry in the favorite properties under the Connection dialog set to "-1" (Unlimited)?
