FTP Voyager Schedular does not copy all files from server to local share

We have noticed that Voyager does not successfully copy all files from our Serv-U server to a local share when writes are happening simultaneously at the server. Most of the files get copied just fine and all files show up in the Voyager log as copied. We are running Voyager Version 16.0.1.1 on a Windows 7 Enterprise OS. The system is a Virtual Server.

We are positive that if we are not writing files to the Serv-U server at the same time as the Voyager schedular is trying to process files, everything comes down just fine. It  only seems to be an issue during a write to the Serv-U system.

Thanks!
