Hi Guido, Where is it crashing when you had "several configs" on the server side? Few checkins went yesterday and daybefore which might fix the problem. Can you check with the latest code and see if you still see crashes? If yes, please help us fix them. And you spec files look OK. You can also use io-threads and io-cache on the client side to improve performance.
