    Kicking sessions because of too many failed commands

    Kicking sessions because of too many failed commands

    Q: Dear support team, With one of our vendors our IP has been banned for invalid commands .

    2024-01-04 01:20:56,152 WARN [com.dymmyhost.mft.port ][6353] – |—Kicking sessions because of too many failed commands.—

    Looking at our log, I could see the error

    1/8/2024 9:31:48 AM SFTPRemoveFile, SB Delete Exception: %DELE-not found%

    What is that? Please consider that we use the option: “use .tmp extention”

    Regarding the .TMP extension, we used it to avoid that the 3rd party could get it before the file transmission. I don’t know if this is related to the error.

    A: This option is helpful when uploading large files and to prevent another process from picking up the files from the SFTP server before the file upload is complete as you said. We upload the file with a .tmp extension, for example “MyUpload.pdf” will be uploaded as “MyUpload.pdf.tmp”. When the upload is successful we first try to delete any existing “MyUpload.pdf” file on the SFTP server and next we’ll rename “MyUpload.pdf.tmp” to “MyUpload.pdf”. The fact that we are trying to delete an non existing file is giving you the issue with this SFTP server it seems.

    Reply Customer: For these jobs we use unique and progressive file names, so there is no possibility to have 2 files with the same name. For us is much better to manage this kind of exception instead of sending a command that periodically makes our IP banned.

    A: In version v2023.1.14.0 we added the following option ‘Use Temp Extension Method’.

    Open your SFTP as Destination setup and witch to the ‘Common’ tab. In your case (unique filenames), you could switch to ‘Rename Only’.

    • Default (Try delete before rename)
    • Check file exist before delete & rename
    • Rename Only

    If you need any help with this ‘too many failed commands’ question, please let us know.
