Freestyle rendering using over 100GB of ram for specific frames
Exact steps for others to reproduce the error
Load provided .Blend file, hit render, wait.
Memory usage has made it up to over 138Gb (using swap files of course), and render of this frame never seems to make it past "Freestyle: View Map Creation"
This animation was taking just minutes to render each frame, up until about frame 330... when the camera turns, and actually sees very little.
Each frame was taking exponentially longer, and I have not been able to render frame 339, even after an entire day. Cancelling the render with ESC key, blender responds, and shows that it is cancelling it, however memory usage sometimes will still increase and I can no longer quit Blender without a force quit. It seems that if I cancel it before it gets up to about 60GB of memory usage, It will cancel, but the memory isn't freed up until I quit Blender. This sounded similar to some previous memory leak issues with freestyle I read about on here, so I tried adding in a few more objects, of larger, and much smaller sizes... It showed a tad of improvement with the freestyle render, getting to 100% faster, although still was not able to actually finish the render.
I'm kind of new to Blender, so If i've overlooked something, sorry to take up your time! Don't hesitate to ask me any questions! I'd love to help squash this!
Thanks

As this ticket is about a possible memory leak I tried to reproduce the leak, but was not able to do so. This scene is too complex. Memory leaks should also be detected with smaller scenes. So will mark this issue as Invalid. Please upload an as small as possible blend file that shows the issue at hand.
