I am not sure under what circumstances this occurs but I've seen what appears to be transmission characters corrupting larger files when transferred to some, but not all, SFTP servers. In the case I saw this was on > 500Kbyte files (but may occur on smaller) being transferred to a MOVEit Transfer SFTP server, version 12.0.2.149.
This appears to be a bug in the underlying JSch library in version 0.1.53 or earlier. See the JSch release notes here: http://www.jcraft.com/jsch/ChangeLog
I have tried bumping the version of JSch to 0.1.55 in my codebase and this appears to resolve the issue although I have not fully tested all the features of clj-ssh under that version.
