How to raise exception immediately when upload target folder is full

Hi, I'm a new comer for the WinSCP script programming. Currently I'm using the PowerShell to do an uploading function using Session.PutFiles. But I meet a difficulty.
For example, I will uploading a 12G files to a 10G free space folder such as /home/foo/xxx use the "Resume" upload option. The uploading will continue till the 10G free space filled. But in this time, it doesn't raise exception immediately but still try to upload until almost one hour later. Then it raises error like

Exception calling "PutFiles" with "4" argument(s): "Timeout waiting for WinSCP to respond"

I wonder to know if there is a way to raise exception immediately when the space is full. If not, how can I set the upload timeout value to a short time?
Thanks

Please attach a full session log file showing the problem (using the latest version of WinSCP).

Hi I have attach the session log. I have upload a file which size is over target folder volume. And I add a method to monitor progress. The space is over when progress is 45, like following.
-Join Current progress 0.39 under speed 13655466
-Join Current progress 0.39 under speed 13956682
-Join Current progress 0.4 under speed 14171180
-Join Current progress 0.41 under speed 14342779
-Join Current progress 0.41 under speed 14404982
-Join Current progress 0.42 under speed 14557277
-Join Current progress 0.43 under speed 14718151
-Join Current progress 0.44 under speed 14861829
-Join Current progress 0.45 under speed 15036323
-Join Current progress 0.45 under speed 14996517
-Join Current progress 0 under speed 0
-Join Current progress 0 under speed 0
-Join Current progress 0.45 under speed 38874000
-Join Current progress 0 under speed 0
-Join Current progress 0 under speed 0
-Join Current progress 0.45 under speed 38874000
-Join Current progress 0 under speed 0
-Join Current progress 0 under speed 0
-Join Current progress 0.45 under speed 0
-Join Current progress 0 under speed 0
-Join Current progress 0 under speed 0

Then I ctrl+c the script. Please check. Thanks

The problem is that your server disconnects the session, instead of only failing the upload. So WinSCP keeps reconnecting, until it timeouts. All checks that would allow more graceful end of the transfer fail, as the reconnect always succeeds. So WinSCP still keeps seeing the problem as temporary.

Hi Martin,
Thank you for your reply. Through your information, it seems that reconfigure server behavior is the best solution. But I haven't authority to change the server environment. Can I have a method to short the retry times? Or short the timeout time?
Thanks

I'm, not sure how it would help. WinSCP does timeout eventually. What other behavior are you looking for?

Hi martin, is there any way to short retry times or timeout time when meet this situation?

Try setting to Session.Timeout to a lower value than its default 60 seconds.
