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.

I started to copy folder from remote server. In the middle of process I turned off VPN and my connection was killed. After some time I enabled VPN and tried to restore connection, but it was failing (usually it works). Then, after some time, connection was restored and I tried to copy the folder again. And received this error.
I don't know how to attach session log

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
Happened during an overnight extremely large file transfer from unix server over VPN to hard drive. Has not happened previously. No one was here, so no keys pressed. However, VPN disconnected and this was shown on the prompt to reconnect (again, VPN disconnects have happened before without this issue).

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.

I changed the option in Options -> Preferences -> Transfer -> Background -> Transfer each file individually on background by default and received the error every time it tries to spawn another thread to start the file transfer. If I un-tick it, everything works as expected.

I've never seen this before - all I did was select 9 files on a remote server (SFTP) to download to my local PC. I pressed the download button and almost immediately got the "Invalid access to memory error".

One of the rows in my queue is marked with a red X and says "Error", three others say "Query" which is unusual for me.

Other possibly useful things - I'd just started Windows from hibernation and it may not have finished starting up completely. Also, at the same time it's downloading Windows updates.

Cheers,
Ralph

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.
