Title:
memory leak in unity-panel-service

This bug affects me on Ubuntu 16.10, after upgrading from 16.04.
Keeping my computer on simply results in unity-panel-service to use up all
memory.

unity-panel-service is not leaking memory on 15.04+. The memory
footprint tends to grow slowly but that does not mean there is actually
a memory leak, it's just the way the kernel manages the memory. Please
reopen the bug if you think the leak is still there.

I'm still seeing this with Ubuntu 14.10:
3381 james 20 0 825M 219M 11672 S 0.5 2.8 1h10:23
/usr/lib/unity/unity-panel-service
I've attached /proc/`pidof unity-panel-service`/maps
** Attachment added: /proc/`pidof unity-panel-service`/maps
The same on my PC. Top output:
PID USER PR NIVIRT RESSHR S %CPU
%MEM TIME+ COMMAND
3213 h1bymask20 0 1068m189m 3356S4 2.5
401:09.53/usr/lib/unity/unity-panel-service
I've just rebooted, so I don't have this in front of me any more.
I don't run any non-standard indicators. I have an external (to the laptop)
monitor and I run unity-2d.
Indicators I have (sorry for ignorance here):
* mail envelope (messaging) : ** this has xchat-indicator in it
* battery
Running since May 3 (18 days now), unity-panel-service is 400M of resident
memory.
The executable running is from 5.10.0-0ubuntu6 (precise release).
So, there is still significant memory leak there.

Scott, using valgrind to find memory bloat (which might not be memory
leaks) is often misleading and inaccurate. The valgrind tool for
measuring boat is massif. Please try that (valgrind --tool=massif).
Also, obviously, if you're running any non-standard indicators then please say
so. Or just
$ dpkg-query --show unity-services
unity-services 5.10.0-0ubuntu6
Attached is a valgrind log for ~ 24 hours using the above version,
showing:
==28208== LEAK SUMMARY:
==28208==definitely lost: 34,549 bytes in 419 blocks
==28208==indirectly lost: 65,745 bytes in 2,510 blocks
==28208==
Thank you for your bug report, quite some leaks got fixed since you
reported the issue, is that still happening? Could you get a valgrind
log for it?

I disagree with the response here for the following reasons:
* marking it 'invalid' so it will magically go away isn't helpful for anyone
* suggesting that I should log out of my currently running environment, and
run valgrind on my system for the next 2 weeks because you find that
* marking it 'invalid' so it will magically go away isn't helpful for
anyone
it's not marked invalid, it's marked incomplete as needs extra
infos, we can't do a lot without that
* suggesting that I should log out of my currently running
environment, and run valgrind on my system for the next
Discussing on IRC, we have some known leaks but most have been fixed,
the issue is likely coming from an indicator but without a valgrind log
it's hard to figure which one...

I apologize for my rant.
I've got valgrind running on my unity-panel-service now, by doing this:
sudo mv /usr/lib/unity/unity-panel-service
/usr/lib/unity/unity-panel-service.real
sudo ln -sf unity-panel-service.wrap /usr/lib/unity/unity-panel-service
cat EOF | sudo tee -a
