-------------------------------------------------------------
I have tried the code you mention - though not exactly as it appears - and it
worked without a hitch. In this context, please try using the built-in
{{SshServer#main}} as-is and see if you can re-produce the problem.
{quote}
none of them work with files of a certain size
{quote}
- What size(s) (*exactly*) ?
- Is it reproducible each and every time ?
- What environment are you using (O/S, Java version) ?
- Is there anything special about the files - e.g., symlinks, NFS mount, other ?
- Have you tried the latest (snapshot) version - it contains an interesting fix
- SSHD-728 - that may be pertinent to this issue.

> SFTP - Some files truncated on retrieval/download
> -------------------------------------------------
>
> Key: SSHD-725
> URL: https://issues.apache.org/jira/browse/SSHD-725
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 1.0.0, 1.2.0, 1.3.0
> Environment: Various flavors of Linux (ubuntu xenial, centos 6, AWS
> AMI 2016.x)
> Reporter: Russ Tennant
> Assignee: Goldstein Lyor
> Attachments: download-lftp-script-output-trace.txt, test-download.data
>
>
> When retrieving files (depending on file size), the files are truncated. We
> have also experienced a similar problem on file upload where we get extra
> data repeated from the last packet received.
> I don't have a test-case for the file upload issue - yet. Still trying to
> find the magic file size.
> I created a github project that demonstrates the truncation issue on
> retrieval.
> Project: https://github.com/VentureTech/sshd-test
> Example lftp Script:
> https://github.com/VentureTech/sshd-test/blob/master/download-lftp-script.txt
> Example lftp Script Output:
> https://github.com/VentureTech/sshd-test/blob/master/download-lftp-script-output.txt
> I used lftp to demonstrate the issue, but it happens with all clients I've
> tried (openssh, Intellij IDEA, kde's sftp ioslave).
> There is a gradle task lftpDownload that will start the server and run the
> lftp script.
> {code}./gradlew lftpDownload{code}
> Attached is the data file I used to trigger the issue.
> In the referenced example output lftp terminates the retrieval with the
> following
> {code}
> [116371] 2017-01-16 15:27:32 localhost <--- got a packet, length=120,
> type=101(STATUS), id=12
> [116371] 2017-01-16 15:27:32 localhost ---- status code=1(EOF),
