Duplication Warning: Sequence contains no elements

[aldinach]

I have a rather large drivepool that has had duplication warnings for quite some time now.  The errors are all the same, where it lists a long directory/filename and ends with "sequence contains no elements."   I've tried to fix this by "duplicate now" but the errors never go away.  Can you advise what this means and how I could fix it please?  Thanks!

Thanks for answering @shane.  Turns out I had a disk that was failing and needed to pull it from the pool and replace it.  Support helped me through the process and the software worked exactly as it should have.  Victory!

Hmm. How long is long? Or (wild guess) the long directory/filename contains unusual/mangled characters which the duplication process can't parse correctly?

Do the drives in the pool all pass a "chkdsk" command?
