I am not sure if the problem has been fixed. Memory usage is still growing for

I've lost count of the leaks in unity I've looked at today (to fix bug
769957). My plan is to only fix what I need to to resolve that bug and
leave the others to this bug (or others).
The most common cause I've found is total misuse of the nux::Object
referencing model throughout the unity code.
Ty Reinhard/Robotex/Krister I have now also disabled indicator-multiload.
I have only just disabling it a few minutes ago but indicator-multiload seems
very likely to be the culprit as compiz (in unity) is no longer eating up the
comp:s. memory.

... cudos Cliff Stewart for finding this one :) compiz is a lot less
aggressive in eating memory now, indicator-multiload is either doing
something wrong that causes memory leaks in compiz or is in heavy use of
some api function that causes this big leak.

There is also discussion of indicator-multiload as the source of the
memory leak in #720446. Look in particular at comments #42 and #44
there. These say that: 1) the leak does not occur when using indicator-
multiload in Classic, only in Unity; and 2) indicator-multi-load is,
every second, loading
indicator-multiload in classic ubuntu and in unity are different things.
The has different source code.

@Robotex: Yes, that's true, but it misses the point I was trying to
make. There is the system indicator applet (which lives in the gnome
panel) that *looks* just like indicator-multiload (which lives in the
indicator area), and I agree that these are different programs with
different codebases.
For the indicator-multiload leak, there is a nice valgrind log at

I will change the behavior of Object::UnReference. I think we could make it so
that it releases objects with a floating reference. Right now, you have to call
Object::Dispose to release an object that has a floating reference.

Thanks Jay. I will try that change too and then only worry about the
remaining leaks after that. Changing just Object.cpp in nux should
eliminate the need to fix much of the unity code, or even worry about
finding all instances of that mistake.

I have tested my suggestion - removing the if (!OwnsTheReference() )
blocks from Object::Reference and Object::UnReference.
The good news:
* Unity is stable with the change.
* The corruption described in bug 769957 and seemingly due to window/nux leaks
is half fixed (but not fully)
The bad
I no longer have the problem if I disable indicator-multiload.

This is a friendly question...
why is the importance of this bug medium?
Compiz uses half my memory. After using my computer for a couple hour I have to
reboot.
On my other old machine, the computer become unusable after a shorter amount of

On my Lenovo desktop (ThinkCentre 8810-AA5) with an Intel graphics the leak
problem only occurs when using Unity. If I select the Ubuntu Classic (compiz
without the Unity) the compiz process does not seems to leak any memory.
So the problem seems to be more related to the Unity, not to compiz.
Confirmed here on nVidia (Lenovo T61) and Intel (Lenovo ThinkCentre 8810-AA5).
Steps to reproduce:
* minimize and restore a window (gnome-terminal, for example).
* drag a window until touching the gnome-panel on the top.
* maximize and restore a window.

alf, with the steps you provided i cannot reproduce any memory leak
here on intel gpu. I might try it on nvidia when i have the access to
it.
