Random crashes with MR (big surprise). Any tips?

[ActionArt]

I'm doing a fairly basic industrial animation using MR. I've had a significant number of seemingly random crashes. This happens on two different machines (one Win7 64bit, one Vista 64bit). I'm using 2012 SAP.

If I work for a while, then render, it will render a random number of frames and crash. Then, if I re-start the project (either from the beginning or from the crash point) it will go just fine indefinitely. However, if I stop and do some work and then start rendering again, it will do that same thing at some unpredictable point (15 -300 frames in).

It never seems to happen when I render single still images. It's nowhere near running out of ram.

I've tried every setting I can think of with no effect. The error message is "Unhandled Exception" which doesn't mean much to me. I know this is probably par for the course with MR but if anyone has any tips that might avoid this, it would be much appreciated.

I think there is a chance you'll solve this by forcing MR to render in chunks of about 10 frames, or even every frame. In this way, MR cache is released, for each chunk MR gets a "clean" data. Method was well known in times of XSI 5 or 6. So you'll render a sequence of stills, literally.
For "every frame" render there is a small nice script at the end of [url=hhttp://www.mootzoid.com/wb/pages/documentation.php]PDF docs of EmPolygonizer 1[/url]. Hope Eric Mootz wouldn't mind my 'abusing' of his docs....

Thank you very much, I'll give it a try.

Ignore this post - testing

Could try unchecking "On-Disk Framebuffers" in the Frambuffer tab of the render options - might help?

I tried that but no effect. So far, rendering individual frames is working but a lot slower so not a perfect solution.

Just in case anyone else is having this problem, the solution for me was to to Enable "Convert Textures to Memory Maps" in the global render settings. Not sure why as there is lots of ram left when rendering but this cured it in this case.
