Got this error when pxebooting our ZCM10.3.1 server, when image copying is about to start.

"...Deconpression error occured

ZENworks imaging failed with error:42...
..Exiting: Computer has not been recently imaged."

We have cleaned the computer with zisedit -c.
There is a hw rule set "no ram < 10MB" pointing at the image bundle.
Have restarted all services more then once.

What could be the problem?
