While rendering a quite complex scene POV-Ray beta33 stopped after 15
hours (and 93% finished) and the only message on the message pane was
"Render failed!". Nothing else.
Hum. This is a bit laconic.
I've already done a lot of test renders with this scene before and it
never made any trouble.
Sorry to be not of much help here but I do not see how to narrow down
the problem, just thought I should mention it. The scene did use
radiosity, scattering media, meshes, hight fields and csg. System is
Windows XP SP3.

As an aside when I was rendering with POV-Ray beta33, recently. My laptop just
shut down with no warning. I was able to finish the render using the +C command.
I hope that you get your image finished in tine ;)

Um... yes, I guess it is ;-)

Given the render time it may be a bit much to ask, but... is that
problem reproducible?
(If so, then it would probably make sense to send the scene to one of
the developers for further experimenting.)

Can you give some indications about scene complexity (number of objects,
size of bitmaps used, and such)?

I'm not sure but I did various tests with one or more 'slow' features
disabled and it did work. I also did a low resolution render (about 120
x 80 pixel) with all features and it did also work. A test with MegaPOV
did indicate a peak memory usage of about 1.1 GB with 2 GB installed, no
other application was running and no tasks like virus scanners in the
background, output was OpenEXR and the display window was disabled
(display=off in povray.ini).

If you have not already done it, you might try the start row and end row options
just around the 93% completion point as a way to take a 'shot in the dark' at
reproducing the problem without re-running the entire render.
On a *nix machine the additional command line flags would be +sr0.9 and +er0.95.
There are 'ini' forms of the options, but I don't recall them off the top of my
head.

On the Windows version (don't know about Mac) you can use CLI options in
the editor (there's a field next to the resolution selection box for them).
