Dear Stefan!
Thank you for your answer. That is what we think. Unortunatelly EULA states:
"A Concurrent Device may be a Client Device, a Non-Human Operated Device or a Process. The Licensee may have in use at any given time a maximum number of Concurrent Devices accessing the Product, or ccessing an application which can access a Product, as purchased under the Concurrent Device License."
In addition PSC said, Policy Guideline is for internal use only, and EULA overrides any other rule.
Now they want sell more licenses for background processes (we did not count in the past). And of course pay penalty retrospectively

I think it is not fair, we used policy guidline rules for internal audits, and EULA does not specify counting methodology.
PSC also states, EULA overrides Partnership Agreement contract, but it is a different story ...
Has someone had similar experiences?
Thanks,
