unity-panel-service memory leak

[Hernando Torque]

There are a couple of similar bugs, this one is about the network indicator (nm-applet). Opening and closing repeatedly will increase the memory consumption by

TEST CASE:
1. Run while true; do ps aux | grep unity-panel-service | grep -v grep; sleep 1; done
2. Monitor the sixth column
3. Open and close the network indicator
4. Go to 3.

→ memory consumption should rise pretty fast.

Valgrind log of opening and closing the network indicator a couple of times (total runtime 5 minutes).

Confirmed following the test case.

Easily reproduce able. nm-applet might also be related in the cause of the problem.

Also scrubbing though the menubar also causes memory leak to a great deal

I use the panel all day at work. After 7 days uptime, unity-panel-service is using 2 GB of memory. Ubuntu 11.10 64 bit, Unity 2D.

Running 12.04 with repos updated multiple times daily - my unity-panel-service is at 652 MiB . Please let me know if there is anything you need for debug.

unity-panel-service was up to 3 GB when I killed it today on my work machine. I've been running Linux Mint on personal machines these days because of the extreme nature of this memory leak.

[abitwise (abitwise)]

I just browsed a bit of net with Firefox and then the machine was idle most of the time. When i returned unity-panel-service takes 6.4 GB of result set and 11.9 GB of virtual memory. This all consumes my 8 Gb of RAM and 8 Gb of swap space.

I have 64-bit Ubuntu 11.10 with latest updates. This problem has occured at least 3 times in the past month.

I don't seem to be able to reproduce the bug with the test case in the description in precise. Hernando is that still an issue for you?

[Hernando Torque (htorque)]

Sorry for the late answer → no, I cannot reproduce the leak anymore. nm-applet seems to be busy producing bug 930491. ;-)
