Mload - Access module error '33'

Hello,
 
for the past couple of days, I am unable to solve my issue. I have consulted our "Teradata" gurus and even with fresh installations of TD client and ML module, the same issue persists:
15:30:52 UTY4019 Access module error '33' received during 'File open'
     operation: 'Attribute name not recognized by attached AM'  File Name :
     '/xxx/xxx/DSD/log/DSD.DSD.out'.
MLoad is being called in DataStage. This is a simple Mload job. This job has been tested on a different server, using the same permissions, login details etc. etc., without any hiccups. 
While the error refers to a missing file, or 'Failing to open', this file is in fact present while the process runs. It is created by the process, and the *.out file is the named pipe file.
As mentioned before, the user has permissions, in fact in the same location error logs are created by this user. 
This error occurs in the MultiLoad Acquisition Stage.
I would appreciate any kind of help or push in the right location.
 
Thanks
