  • User-554221838 posted

    Hello,

    We are getting errors on our FTP servers when users try to upload files. Some of them succeed but some of them failed.

    FTP server: Windows Server 2003 Standard SP2
    IIS 6.0

    These are the return codes extracted from the IIS logs:
    #Fields: time     c-ip           cs-method     cs-uri-stem     sc-status sc-win32-status
             00:00:01 217.*.*.*    [168840]sent   123.ZIP           226            0

             00:00:01 86.*.*.*     [166627]sent   456.ZIP           426           997

     


    Could someone please tell us what does this codes means and how could we solve it.
    Thanks.

    Hi,

    I'm not familiar with that error I'm afraid but my best guess would be that two processes are both trying to access the same file simultaneously. I think some FTP clients allow multiple threads and perhaps this is causing a locking issue ?

    Regards,

    Hi,

    A 226 status code is a success but a 426 means :

    "The command opens a data connection to perform an action, but that action is canceled, and the data connection is closed."

    There could be any number of reasons for this, such as network issues, etc.

    Regards,

    Thanks Paul. I know 226 is a success. You can see error code 997 followed 426.

    997: Overlapped I/O operation is in progress

    What causes this?
