Not a fix, but a workaround: Each time app_indicator_set_menu() is called, we leak by 200k. so, I reduced the number of times it gets called. (Currently called any time a device is updated, which seems to happen every 30 seconds. Devices are updated even if nothing has changed.)
I'm rather novice, so I've probably fudged something else up by doing this. It works for me (desktop, wireless mouse being the only battery indicator I have) I couldn't make heads or tails of the actual leak itself, though. The attached patch has been applied to package, and uploaded to my ppa:aaron-haviland/ppa for Maverick. I've also applied it to the Lucid package and uploaded, but I don't have a lucid system to test it on. After running for 2 hours, according to /proc/pid/smaps Rss has only increased by 240kB ** Patch added: "15-bug569273-leak.patch" https://bugs.launchpad.net/ubuntu/maverick/+source/gnome-power-manager/+bug/569273/+attachment/1760173/+files/15-bug569273-leak.patch -- You received this bug notification because you are a member of TI OMAP Developers, which is a direct subscriber. https://bugs.launchpad.net/bugs/569273 Title: memory leak in gnome-power-manager Status in Application Indicators: Fix Released Status in “gnome-power-manager” package in Ubuntu: Invalid Status in “indicator-application” package in Ubuntu: Fix Released Status in “gnome-power-manager” source package in Lucid: Invalid Status in “indicator-application” source package in Lucid: Triaged Status in “gnome-power-manager” source package in Maverick: Invalid Status in “indicator-application” source package in Maverick: Confirmed Bug description: TEST CASE: (at the beginning because it's a long post): 1.

I witnessed it using up to 120MB in the RES column according to "top". My machine is 64 bit and is connected to a APC uninterruptible power supply. I haven't yet tried unplugging it to see if the UPS is somehow related to this problem. Another person reported a similar problem in bug #196688 comment 25. Opening a new bug seemed like a good idea since that bug was fixed 2 years ago. Here is some information for what gnome-power-manager looks like after running for a long period of time (from /proc/`pidof gnome-power-manager`/smaps): 0147b000-08810000 rw-p 00000000 00:00 0 [heap] Size: 118356 kB Rss: 118188 kB Pss: 118188 kB Shared_Clean: 0 kB Shared_Dirty: 0 kB Private_Clean: 0 kB Private_Dirty: 118188 kB Referenced: 118020 kB Swap: 0 kB KernelPageSize: 4 kB MMUPageSize: 4 kB I rebooted my machine and let it sit at the login screen.
