System Information
System 1: Win 10 64x, 16 GB RAM, NVidia GTX 1080
System 2: Win 7 64x, 8 GB RAM, NVidia GTX 1050

Blender Version
Broken: 2.78a e8299c8 and 2.78b (unknown hash)
Worked: None

Short description of error
Files are based on this tutorial: http://blenderdiplom.com/de/tutorials/all-tutorials/617-tutorial-tintentropfen-wasser.html

During bake or animation render process, blender is closing without error message. It seems to have something to do with the complexity of the Scene, the amount of Divisions set for the domain resolution (smoke) and the available RAM since Blender closes at an earlier frame on my Computer at work with 8 GB RAM compared to my Computer at home with 16 GB RAM.
Reducing the amount of divisions seems to help. I can render the attached file "2 drops.blend" with a value of 448 at home and it crashed with 512. At work I have to use 256.

When I added 2 more drops, it now crashes at home at 448. I haven´t found a working value, yet.

Exact steps for others to reproduce the error
You will most likely see the Crash, when you use 4 drops.blend (more complex Scene) and set divisions to max (512) . Then bake.
2 drops.blend
4 drops.blend

Looking at the description its a simple out of ram issue.
Some things can get quite out of hand when it comes to ram use.

Try running it with a system monitor and see if it runs against the max, if so, its probably a lack of RAM.

Thanks, Joey.

Yes, RAM use is running against the max and I agree that this is probably a lack of RAM issue.

But shouldn´t there be an error message? I mean at least. Maybe there are even ways of improving Blender to prevent out-of-RAM-issues?
Does Blender use the virtual RAM? If so, can I just increase the amount of virtual RAM to prevent the crash? But currently the OS is managing my virtual RAM and should increase it automatically if needed. Obviously that does not work, so that I assume that the virutal RAM is eiter not used, or not managed properly by the OS or the maximum amount of VM is also reached and cannot be increased any further.

Anyway, I am changing the status to resolved.

Thanks again!

No problem.

Managing RAM use is not something easy to do, since it would mean that Blender has to be aware of everything the operating system is doing, which is not the task of a application.
Unfortunately this is a tricky issue.
