I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
I try to drag and drop a relatively large file and it fails, have tried multiple remote targets over SCP.

Hi,
i joined a screenshot, i'm trying to copie a 4.5 Go dump file (binary mode) by drag&drop or menu, the error is the same. The distant server is a linux centos 6.9 in a VM from oracle virtual box launched on the machine where i'm trying to send file from... I installed this version because i already met this error with the previous version. This file was already transfered from an other linux VM from an ESX, not my PC without any pb.

Hi,
i retried the transfert (i really need this file on the other server) while forcing the binary mode and then it's working...with the right click command + binary => without forcing the binary option, i have the error.

I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

I've run the debug version but unfortunately it doesn't replicate the issue. The debug version works. I can't email the trace log as even zipped up it is 65Mb (unzipped it is 2.43Gb).

The previous file (GipAccept.sql) was successfully transferred by sending it as a binary. It could be the windows-to-unix conversion that takes too much memory. Hop this helps
