I'm using Directory Opus 12.7 Build 6540 to upload files to a FTP server (Cerberus FTP, latest version downloaded today).
When I upload, for example, a 18.9KB file (it's a text file, html), the file just uploaded in the server is 16.00KB. When I login to the server via remote desktop and open the file with a text editor, I see that it has been truncated somewhere in the middle.
Then I try to upload it again and this time the uploaded file is only 14.3KB.
Then again and again and again, until 8 or 9 tries later, the file is uploaded correctly.
If I upload it again, then maybe it will be only 14.8KB again.
How can I debug this error? I've been using both Directory Opus and Cerberus for a very long time without problems. This problem only appeared a couple of months ago.
