I confirm the problem.
It disappears if domain resolution is increased to 33 divisions.
it works here with res 29 and 31 zeauro
but if you move the collision object down it fails again (also with res 35 etc - seems to be random)

Seems like it kindof reacts to the collision surface, but only halfway :/ @LukasTonne?
@LukasTonne, it looks like this has never worked and may be due to our poor particle system, so let's move this to the Todo?

@JulianEisel, i don't see any relation with particles here, Please be more accurate with investigating the issues and giving clues.
I think this is related to the adaptive domain feature: when i disable this, resize the domain box to include the emitter, and increase the division for roughly equal cell size, the problem disappears and collision keeps the interior free.
More testing: Moving the obstacle object away from the center axis also seems to "solve" the issue:
This could indicate an alignment issue: notice how the first case still shows the problem on one side, where the offset is less than one cell.
