unity-panel-service Leaks Memory

Bug Description

Binary package hint: unity

This isn't related to bug 722972 as using the global menu does not affect the memory usage.

Over the course of a day or two I find that the unity-panel-services service uses over 100 MB of RAM. I do not know what triggers the leak but once I end the process and it respawns it backs down to the ~6 MB that it should be using.

I've been watching it since this morning, no increase in RAM usage... I'm wondering if it your suspending / resuming your computer a lot duing that time? Or a lot of loggin in / out? What kind of use does the computer get?

It's two computers. One with nvidia proprietary and one with intel onboard. I do suspend and resume my computer very often. I also use the indicator-sound for music changes often as well.

Muratov, can you still reproduce this? If so, please mark this as confirmed.

Chauncellor, Muratov: Do you have additional time zones configured in indicator-datetime? If so, this could be a duplicate of bug #801709.

I do not.

Chauncellor, Muratov: Do you have additional time zones configured in indicator-datetime? If so, this could be a duplicate of bug #801709.

Hi sorry, but i am no configured any in indicator-datatime. I am replace Unity3d on Unity2d. Unity2D working good. Time zone configured during installation.

Same bug here, after 11days of uptime, Unity-panel-service is eating 205MB.
I never use sleep or suspend, my PC is always on.

Ubuntu 11.04 amd64 default setting except I added the weather Indicator to the pannel (Weather Indicator 11.05.31 'Cloudy 8')
My hardware :

Core i3 540, intel graphics, 2Go RAM

I am having the same problem. Unity starts at less than 6Mb and in two days is over 130Mb. AMD64 system using nvidia driver. I am also using the weather indicator in the panel.

AMD dual-core 4600, 2Gb RAM

Fix for indicator-power commited in trunk: http://bazaar.launchpad.net/~jjardon/indicator-power/master/revision/103

These leaks are caused by indicator-power (which we are running in-process, so it looks like panel-service is leaking). Going to mark as fix-committed per Javier's comments. NOTE: To re-iterate what Hernando said, this does not include the indicator-appmenu leaks.

This bug was fixed in the package unity - 4.14.2-0ubuntu1
