Fixed. The feeder is now back to a couple of MB.

Is the storage service really taking 100mb? If you can reproduce this, do
you think you could run it in massif for a while so that I can see what is
consuming all that memory. It ideally shouldn't go about 20-30mb.

Virtuoso is just .. :/

From a Nepomuk point of view, consuming 50-100mb for all of Nepomuk is
acceptable. Anything above that is not. I can bring down the memory usage
of all of the Nepomuk parts. I'm not sure what I can do about virtuoso,
though.

Anyway, we cannot really block the marketing announcements cause Nepomuk is
consuming too much memory.
