System Error 998 when uploading >2GB files to S3

Hi Martin,

Uploads of very large (video) files to S3, apparently >2GB, fail with a error box saying:

Error reading file D:\Users\filepath\file.mov
System Error. Code 998.
Invalid access to memory location

Uploads of less than 2GB or thereabouts on the same filesystem work fine (working examples were 1.6GB). Files can be opened locally in other tools.

Observed on WinSCP 5.13 (Build 8172) on Windows 7 Enterprise SP1
Also observed on WinSCP 5.13.1 (Build 8265) on Windows 7 Professional SP1

Upgraded WinSCP to get S3 functionality, so cannot refer to earlier behaviour.
Protocol: S3
Interface mode: GUI, using Commander Mode

Steps to reproduce:
Find or create a local file greater than 2GB.
Navigate to local and remote (S3) directories.
Drag local file onto S3 side of the commander interface
Transfer popup window appears, then the Error popup window appears within a second.

I've attached a log and a screenshot.

Thanks for looking at this.

Daniel

Re: System Error 998 when uploading >2GB files to S3

Hi Martin,

The new version you sent appears to fix the problem, thanks.

I successfully uploaded two 4GB files to S3 today, without any problems.

My colleague, who initially alerted me to the problem, was not successful on several attempts, claiming the uploads failed spontaneously variously at 40-70% complete - but I'm uncertain if his machine tried to sleep, or his internet access service glitched or whether the ongoing slow upload rate (about 2Mb/s I guess, it is an old HFC service) had an impact. I'll ask him to have another go, and report back.

Regards,

Daniel
