Number of workers still not transfering large amounts of files

I'm trying to upload a folder with alot of sub folders and files. i have 5 workers going however all of them eather say "retry at xxx" or "waiting for children to finish" however nothing is being processed in the que

Let me add this only happens with folders holding a lot of things. It does not happen when moving say 5 or 6 things at a time.

Post the system information from the menu: Help->About "System Information" dialog.
