Blender crashes when adding more objects to fluid simulation

Hey guys!

I’m trying to bake a fluid simulation with only 105 MB of required memory. This works pretty well with four objects such as one domain, one inflow and two obstacles (final resolution 150).

But now if I add in one more object (like another obstacle or an outflow) Blender crashes instantly. The required memory to bake the fluid simulation doesn’t change and it is still very low. I have successfully baked other fluid simulations with much higher values.

How do I accomplish baking a fluid simulation with more than the four objects mentioned at the beginning?

Thanks,
