Hi @meanii thanks for reporting this - If you don't mind sharing, about how many files are you trying to transfer and what size are they? Also, how long did it take before the crash happened?

Do you know what the file sizes tend to me? For small files, you may want use n=1 for the number of VMs, since the bottleneck will be in listing the files.
