Memory Leak? **UPDATED w/Animation***

I'm running mxcl from command line.

At the beginning, each frame of this particular animation takes 3'55" per frame. 12 hours later, each frame takes more than 3 hours to render. If I stop and restart the batch at the last "3-hour frame", it's back to 3'55".

I just setup a new batch and watched the Mem Usage in the Task Manager. The first frame loaded up 133,900K to render. Upon completion, the Mem Usage dropped to 105,000K, and then during the next frame voxelization, shot up to 177, 908K. The thrid frame went up to 233,512K. It doesn't appear to be flushing the memory between frames.

The content of those first 3 frames is nearly identical: A slow camera pan over static objects. With the memory not flushing, I can see how soon the RAM usage will be up to 2GB again, and the render will crawl.

Is this a leak, or a failure to flush, or what?

Can you provide a scene that we can test?

Here is an animation test of the problem scene. Some interesting artifacts showed up during the render.

Thanks.. I'm not really bothering with textures yet, since there's such a huge limitation there (Material Editor's coming). But I thought I'd just start pulling out some animations and see what happens. Right now, Maxwell seems very sensitive to certain qualities of models... this model has never rendered with any glitches in Maya, mental ray, or Renderman, but here there are black spots showing up sporadically.

Light scale seems fairly convincing.

Doesn't read as "model" - even with no textures

I know... it's wild. Any ideas about those sporadic black spots, anyone?

Hi Mike,

We are going to look what is happening in this sequence. Was it rendered with 1.2.2a version and maya plugin, wasn't it?

Best regards.

Yes, Oscar... 1.2.2a, and the latest Mayall.

Thanks so much!
