Thanks guys, it's really bugging me. News on the matter, it was the spinnerettes, when I took her down they snapped and she was free of the old exuvia. She was about 1½ year old, started of 2 mm in legspann. I've got one left, also belived female, but smaller and not as grand as this lady was. The other one doesn't molt from the cealing either, I don't know if that's good or bad. Moisture is not the issue, it's litteraly a swamp under them both.
