I am seeing this with beta 40 as well... and the image is not huge.

Copied biscuit.pov into my $HOME and...

povray +ibiscuit.pov +v +w1920 +h1200 +a0.3

Says:

==== [Rendering...] ========================================================
Intermediate image storage backing file seek failed.
Rendered 1024 of 2304000 pixels (0%)ile seek failed.
Fatal error in renderer: Frontend halted render.
Intermediate image storage backing file seek failed.
Intermediate image storage backing file seek failed.
Render failed

When I do it at a smaller size:

povray +ibiscuit.pov +v +w320 +h240 +a0.3

It works (in 1.345 seconds of trace time, btw -- nice).
