I was testing SFTP transfers and saw this error message get logged:
ERROR [SFTPSubsystem] 13 Feb 2015 16:44:08.887 : VerifyRequestOK: Operation unsupported
Tried to look this up but didn't find anything useful. Oddly, the file was still successfully uploaded, even with this error.
I set the logging level higher and this is what it showed me.
