It might be a bit surprising, but I think Hendrik's reasoning is quite good: you don't want to keep on expanding when there are problems not freeing resources that are limited.

Delayed our deployment of the ESUG registration server for some weeks... normal seaside use, image quites after a day. It's far from obvious. I think the image should work out of the box.
