** Description changed: There seems to be a memory leak in Unity that comes with use (not age). Hardware: ThinkPad W510 (nVidia Quadro FX 880M, driver 304.51), Core2 -Duo-based desktop with nVidia 560Ti (same driver) Software: Quantal Beta, up-to-the-moment updates, both 64- and 32-bit (one of each). *Note: I can *not* test with nouveau. Not only is it completely unsuitable for laptops due to terrible power management, but neither computer will boot with it - I get the PFIFO stuff, even though the -16 kernel was supposed to fix that. Steps to reproduce: 1) Log into Unity and launch System Monitor (gnome-system-monitor). Set to view "all processes" and organize by the "memory" column. Take note of the amount of RAM taken by the Compiz and Xorg processes. 2) Open a bunch of programs. I use: Nautilus, Gnome-Terminal, Chrome, Banshee, EasyTag, EasyMP3Gain, Empathy, Eclipse, and Rhythmbox. 3) Close all of the programs except gnome-system-monitor. Note the increase in RAM the Compiz and Xorg processes take. 4) Repeat steps 3-4. Memory on each process steadily rises. It isn't by a lot, but it creates an environment wherein the longer one uses one's Unity session, the less free RAM one has to work with (as neither process ever seems to give up any of its RAM, ever, not even after 10 hours of use). I don't seem to have any stability or performance issues stemming from this. ALSO: Opening the dash at all raises the RAM usage by a LOT, and subsequent openings of the dash (poking around, clicking on new buttons that reveal icons I haven't seen before, etc) also grows the process's RAM. By a LOT on the first run, but by a noticeable amount on later runs. *I* think this is a pretty high-priority issue, but as the RAM use and growth isn't all THAT large (~0.5/1 MiB every time steps 2-3 are repeated), I could understand if it weren't marked critical... but I think any leak is critical, so there's my bias. STEALTH EDIT: I want to point out that just leaving the system logged in does not cause Unity *or* Xorg to use more RAM over time. Not even with the indicator-multiload running. - STEALTH EDIT #2: All lenses and scopes except the Application lens have - been uninstalled, and do not factor into this. So I'm pretty sure we - don't have a runaway call in any indexer or anything like it. + STEALTH EDIT #2: All lenses and scopes except the Application lens have been uninstalled, and do not factor into this.
