Hi!
I rendered the patio-radio.pov example (with somewhat tweaked radiosity
settings for higher quality) at a resolution of 2048x1536 with AA. It took
about 3 days on my Athlon/500 and all the time the amount of memory used by
povray was steadily increasing (to about 200MB).
Looks like a memory leak to me (or is there a good reason why povray takes
up more and more memory during rendering?).
I can post the exact settings used+modifications to patio-radio.pov here if
needed.

This is perfectly natural with radiosity and 'always_sample' on (default),
samples taken during final trace are continuously stored for possible
later reuse. If you have problems with that either use 'always_sample
off' or render in several parts.

No problem with that (my Athlon's got 256MB Ram and I'm not planning to
render with any higher quality settings). I was just wondering whether it
was a leak.
Thanks for the quick reply!
