How reproducible:
All the time

Steps to Reproduce:
1.Import a folder
2.Display a picture in darkroom, double click on another picture, and another one...

Additional info:
Tested with both JPEG and NEF

and when you click back on an already opened picture, is the memory increasing?

I try to reproduce the problem on my Fedora 16, I get the same result but I'm not sure it's a memory leak, could be just a cache system.

It probably is, the problem being that after ten 12px images, the memory usage is 2.1G even if I set low memory usage limits (800MB for tiles). And then swapping begins and it becomes unusable and this memory seems never to be freed.

Maybe I don't understand how the memory limit works in that case, darktable is just a memory hog and is pretty unusable, even with 4GB of RAM.

Comment 3 Edouard Bourguignon 2012-04-20 15:00:45 UTC

François, I remember some threads about memory usage in the darktable-devel mailing list. I think you should ask there (or in their archives) about your darktable memory usage, to be sure it's not a memory leak. Not sure I can do anything else since it's not a rpm/fedora issue.

I've heard about the 1.0.1 release comming at the end of this month, may be it will adress this issue. I will look for any memory issue in their post-1.0.0 branch.

Comment 4 Edouard Bourguignon 2012-05-10 07:19:50 UTC

1.0.3 is in the updates, and it seems more stable with the memory usage. I close this bug but feel free to reopen it if problem persists.
