  • 1.  SFTP Poller endless loop on long filename

    Hi,

    I'm seeing some strange behaviour at my customer with the SFTP Poller. We are running a MPGW with an SFTP Poller that polls a directory on an AIX machine. 

    The filename is 199 characters, and DP FSH then adds a 66 character long string while renaming the file (including machine name, domain name, FSH name, identifier).

    This bypasses the 255 character filename limit in AIX, and the operation is not permitted, however this does not seem to cause any error in datapower; instead it fails in the next stage when trying to pick up the renamed file (which does not exist).

    We have configured the poller to move any errors to an /errors subdirectory, but this condition does not seem to be met by this failure, and thus the file is once again processed by the poller, failing in the same manner.

    Including a debug log below from the FSH which I believe should be read down->up, but the last two entries seems to be in the wrong order.

    Is my analysis of the issue correct? Has anyone else seen this behaviour and is there a solution to it?

    Best Regards,

    Pwr
