Well, Matthijs was here a few weeks ago. Maybe you should come too? The good
news is that we now also see this behavior in our test setup, which means we
can beat the sh*t out of ods without impacting production.

I think this is somehow the core of the "bug". This keeps increasing and
increasing. Maybe it is related to the signature validity period? I.e. it
keeps increasing for 4 weeks and then it stabilizes, because finally some
