Kopieren von Dateien vom entfernten Rechner schlug fehl - TTerminalQueueStatus::FindByQueueItem

Tried to move a 6.4G big file from a linux server to my local file system way by drag and drop and pressing SHIFT. Put the copy dialog in background and started another move from a different server also with a file with ca. 6.4G file size. Also put the second dialog to background. About 1G were copied of the first file and the the error happened. Never saw this before. Second try to move file with same WinSCP session worked without problems.
