nohup and rapidminer command line

ikunz

I am having trouble running a process that takes loads in an examle set and builds a model and generates it. I am trying to run it on a linux machine using the following command:

nohup rapidminer rm_workspace/UMLOCForEachProject/generateDTMModelForAllProject.xml > generateDTModel.log 2>&1 &


but after a day or so I get the message below that the xserver connection is closed.
Why does it need any x windows?

Hello,

we unfortunately build some dependencies on graphical elements into some of the models (including for example the decision tree model). The latest CVS should have removed most of these dependencies now so upgrading might help. You can get more information about how to access the CVS version and building RapidMiner yourself at

http://rapid-i.com/content/view/25/48/

We are hoping that we removed all of these dependencies already but there might still be some of them at some places. So we really appreciate if you run into these problems after updating.

Cheers,
Ingo
