What happened to the Mental Ray?
This is what I get:
mental ray for Maya 2012
mental ray: version 3.9.1.36, Feb 2 2011, revision 138829
initMPS with licenseOption 0
mental ray: got 8 satellite CPUs.

Is there any way to fix this?

Take a look at your task manager when running the render. Is all of your memory being eaten up? If yes, then you'll need to change some things in your scene. Either that, or buy more memory.

It seems like this setting is useful:5242880 bytes = ~5 megabytes

Export objects on demand and allocate on Heap.
With those two the render seems to be running faster (even though it says it will be slower).
I couldn't check when the crashes happened, but with these settings it doesn't exceed 2.18 gb (out of 4)
3rd picture shows what might be the problem: My scene has these planets far away from the grid and 2 of the objects Sun and Jupiter are slowing down the movement in viewport when both are in the same view (picture 4).
So far it doesn't crash anymore. But I'm still worried about the viewport slight lag.

Also, the RAM isn't even used up halfway when the crash happens.
I can make it crash only from that angle and this is what happens when I render halfway.
I'll try to export stuff separately, maybe the importing had something to do with the problems.
Or the textures.
The entire file has reached 30 mb.

Tried reducing texture size, still crashes when I render from that angle.
Made a new camera... still crashes when viewing that angle.
What I'm suspecting now is the transparent glowing Torus around the planet, but deleting it doesn't really stop the lag in the viewport.
Seems reducing the polygon numbers on the spheres fixes it (I hope it stays this way). I've smoothed all of the spheres to appear rounder, maybe that's what caused the problems.
Yeah, it fixed it. The Reduce poly tool is very useful for this problem. Seems I have to either:
a) Keep the scene limited to a certain amount of polys
or
b) Make sure that the camera only has to render a certain amount of polys, thus some views will not be rendered if too many polys are in the same image.

If you have the time, watch the full thing. If you just want to see what I'm specifically pointing to, go to 22 minutes and 58 seconds. Follow those diagnostics, and see if it still crashes.

Thank you but I've already figured what happened: I exceeded the poly numbers (spheres were double-smoothed and my scene was HUGE). The fix was to just reduce polys on some of the spheres. My scene contains a whole solar system (minus a few dwarf planets and + a few other stars in the distance, the grid is so small now...).That doesn't seem right. Take a look at this:

Now I'm trying to animate it but found out that MR doesn't have the convenient .avi option -_- Now I either have to import 1 image at a time to make a movie in Corel Photo-paint (because bulk import reverses the image order, don't know why) or find some other program that acts like Corel and does bulk import in the correct order + has frame control and export to .avi.

That still shouldn't CRASH mental ray. It should be slow, as it's writing to the disk (virtual memory); but it should still render.I've already figured what happened: I exceeded the poly numbers (spheres were double-smoothed and my scene was HUGE).

Idk but that fixed it for single-frame rendering the moment I've reduced polys on spheres and other objects (the moons had the most polys though because they had irregular shape and such).That still shouldn't CRASH mental ray. It should be slow, as it's writing to the disk (virtual memory); but it should still render.
Then I forgot the Allocate on Heap option on, and the batch renderer began to silently crash.
Good thing I'm out of the woods now.
