Total Commander

Hi. TC version 9.22a fails uploading files bigger than 2MB when using webdav plugin (https).
This was a terrible situation for me, because it didn't show any error in background mode. I decided the upload is finished and removed the source.
In foreground it does give an error without any description.
The webdav server shows the following errors:
[Tue Oct 29 14:24:28 2019] [error] [client ---] Could not get next bucket brigade [500, #0]
[Tue Oct 29 14:24:28 2019] [error] [client ---] Method:PUT. Failed to stat file (/---)

I also checked version 8.52a in another PC, it works fine. Webdav plugin was the same latest version in both cases.

I have had reports of this bug from some users - it seems to be a problem with caching - Windows writes the data of the whole file into a local cache and only uploads it when the file is closed. Unfortunately this function has a 30 second timeout, so the upload fails when it takes more than 30 seconds.

Unfortunately I was never able to reproduce this Windows bug on any PC.

Is there any workaround?

No, I cannot fix this error until I can either find the reason, or at least reproduce it on any PC...
