See attached log for more detailed memory usage. I've checked the mediatomb log's and there doesn't seem to be anything interesting in there, apart from a few warnings about thumbs.db files being corrupt, I'll delete those and see if the same problems occur, I suspect they will, because the problem's happen in folder's with lot's of video's. One question I have to ask is why is mediatomb 0.12 svn in the repositories of a LTS release of Ubuntu, shouldn't the 0.11 official release have been kept? -- mediatomb causes excessive cpu and memory usage with ffmpegthumbnailer turned on https://bugs.launchpad.net/bugs/478236 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
