Error msg copying files >100KB from local to SFTP site

Help & Support

Hello,

I have Directory Opus Version 12.12 x64. When transferring files from my local drive to an SFTP site I receive an error dialog box:

Copy File - Directory Opus
An error occurred copying 'filename.ext': An exception occurred in the service when handling the control request. (1064)

The only error that appears in FTP Logs when this happens is this: "SSH: FATAL: Received unexpected end-of-file from SFTP server".

  • Error only occurs for files greater than 100 KB.
  • Does not occur for regular FTP transfers.
  • I don't have this issue transferring any files using FileZilla.

I think the issue may be on the FTP site, but I'm not sure what I need to ask the site admins to check.

Any ideas?

Thanks in advance.

From our side, it means the file ended before it was supposed to.

Doing a web search on Received unexpected end-of-file from SFTP server shows there can be various causes of the problem, some affecting FileZilla, some Putty, and some both. It's usually something misconfigured on the server side. I don't know which might apply to your particular environment, unfortunately.

Our SFTP code is based on Putty, so asking your admins to check that things are working OK with the Putty SFTP tool is probably a good way to start. Hopefully it will reproduce the error for them.
