Hi BalazRobertSHSTEDCSVKCACHP-0871,
It looks to me like the error was caused by a simple overload on the processing going on during the import of the clone. I suggest that it may not happen again and the lack of information about this error points to it being a rare occurrence. All I can suggest is that in future, you make sure that the server that you're importing onto is not engaged in any other processes.
