3.37.0 & 3.37.1 only : random files not transfered without failure notice, files created with a size of 0 without failure notice, increase of failed transfers

With Filezilla client 3.37.0 and 3.37.1, when I upload large amount of files in several subfolders through an SFTP connection (to an openssh sftp server on debian jessie), I've got several problems :

• Some files go missing without any notice in the failed transfers panel (they appear in the "successful transfers" panel but are not on the server)
• Some files end up with a size of 0 on the server without any notice in the failed transfers panel (appear in the "successful transfers" panel but size 0 on the server)
• I get some "target file already exists" for some new file to create
• I noticed also an increase of failed transfers that I have to reset and requeue (though it didn't occur in the transfer which log is attached)

I could reproduce this problem several times when I upload a large amount of files with subfolder structure, but missing files and 0 size files are never the same and their number varies. It's generally about 4 or 5 for 2000 files to transfer.

I switched back to 3.36.0 and all those problem are not occuring anymore, and they never occured within the last 10/15 years I've been using Filezilla.

During the transfer related to the attached log file, I had 8 files in failed transfer. I reset and requeued and they uploaded correctly then.
Those files are not the one that are missing after transfer is completed.

Size 0 files without notice

Confirmed for overwriting after filezilla asked for overwriting an 'existing file', however folder was freshly created :

I can confirm this issue. Cost me several hours of scratching my head as to why my website wasn't working until I figured out all my files were not copying and some were ending up in the wrong folders (using SFTP with 10 simultaneous connections).

Thanks for your comment. I forgot to mention it in my report, but I also use 10 simultaneous connections.

I can confirm this major issue too. Same problems here:

• Some files with size 0
• Some files sent to wrong folders
• No failure notices

I'm using SFTP with 10 simultaneous connections as well.

Should be fixed in 3.37.3
