Dear Gary, No apologies needed. You just put me on the right track to solve the issue. Actually, there is no explicit need for the cmon plugin on this instance. I used the extension to monitor the hardwae when I first installed. However it is running whithout major issues for years now, and I didn't realy use the cmon extension very often. Anyway, thanks for your further explanation, good to know the ignnored_mounts are configurable after all. Maybe others can use this information as well.
