Short description of error
Hello, i found a bug, this is a trouble for me.
I do render with animeted plane with curve modifier
I can't get clean full animation render, but some frames a good.
Please see my scene

Event Timeline

I did some experimenting this this .blend.

It pretty much hangs on a render of a frame, but is still processing.
I terminated that process.

Changed tile size from 240 x 270 to 60 x 65 and got a frame (frame 28) to render at a slow 11:43 minutes.
Next, turned off motion blur, rendered with 60 x 65 and the frame rendered in 0:41 (41 seconds).
Turning off and on HDR did not make much of a difference.

So the big CPU time consumer (and mine was running into 360% range with 20 threads) was Motion Blur.

Thanks @Joel Godin (FloridaJo) for checking :) Looks like we can call this confirmed.
