Small issue though: besides the earlier mentioned "alpha background" there are artifacts that have no filling, they are exact squares so it are pixels that are not filled with rendered stuff

Luxrender always kept crashing always after ~5 min, so I investigated and saw that the linux OOM killer terminated lux.
I watched the memory consumption and am now able to reproduce the problem. The leak seems to have to do with the film writing turned on, as with each flm write you have a higher step in the memory consumption, allthough once the first time a film is written to disk, memory consumption starts to increase even after each tonemapping step.
See attached zipped blend file for a demonstration of this problem. I used 6 lightgroups and a resolution of 1600x2000, tonemapped tga and exr is written.
Lux starts at ~330 MB and stays there until the first film write. After that its at 530 and continously climbing and will eventually be killed by the linux OOM killer.
( BTW I am using the CVS from 19.03.2009, 10.00 am GMT+1, compiled with intel icc 10.1.018 64bit, linux kubuntu 8.04.2)

loramel wrote:OK, here we go.
See the stripped crown file attached which should produce this problem.
It looks like the thread, which writes the film does actually take longer to write the film than the writing interval is. On my machine the interval is set to 120 sec, but the actual film transmission lasts for ~4 min. So immediately after the film is written another one starts to write again, and here is were the memory gets lost.
When trying out this file, keep in mind that the basic memory consumption when rendering is tarting is 1.2Gb increasing rapidly, so a 64bit machine is probably a must here.
