Not?
RSS keeps growing and growing over a period of just over two weeks in my 
numbers.
It's size more than doubles, even if you use the first proper 
measurement after 24 hours (once every early morning) as a starting point.

Wrong direction.

I wonder

The board can hold 1 GB. It has 1 GB.

You appear unfamiliar with VIA hardware.

Why would I need HD-capable HTPC stuff for my small amount of SD materials?

When will this level out?
I've seen RSZ grow for over 21 days at roughly the same pace.
And as I say, if I let the backend run, the machine will start swapping 
and will eventually crash.
So when will it level out at what size and why?

How do you know when stuff keeps growing in my numbers?

I only posted numbers.

The graphs were not mine. The numbers are. Please have a look.
