compiz leaks memory badly

[Rick McBride]

Binary package hint: compiz

after 24 hours of operation, Compiz is taking 2.6g of virtual and 1.1g of real memory. This is excessive. Clearly there's a leak of some sort. Hopefully the attached apport info will help. This is Ubuntu Natty Beta.

Dual displays.

I guess I beat you... ;-)

Other people on IRC confirmed this issue too.

[Jan Claeys (janc)]

The huge memory leak seems to be fixed with yesterday's compiz upload (there is still another smaller issue related to opening the dash, but that's already tracked elsewhere AFAIK).

@Rick: can you test with the newest compiz (package version 1:0.9.4+bzr20110411-0ubuntu1) and close this bug if it's fixed for you too?

[Rick McBride (rmcbride)]

Memory utilization after 24 hrs operation of the updated compiz is
 3368 rmcbride 20 0 794m 62m 20m S 3 1.6 34:03.43 compiz

Which is far far better. I don't have any tracking data regarding what leaks may remain, but it looks like the really bad one was fixed with that upload.

compiz on my laptop eats nearly 800MB of RAM and it always uses about 25-35% of CPU load. This causes my temps raised up about 5C

[tsaitgaist (kevredon)]

the memory leak is still existing with 0.9.4+bzr20110415.
bug 758248 could be a dup

[Jan Claeys (janc)]

@Hoang: I think this is not the same memory leak Rick & me were seeing.

@tsaitgaist: might be; the original report says "after 2 days" and was filed on the same day as the one Rick & me saw was fixed.

But I agree that there still seem to be some unfixed memory leak(s) in Compiz/Unity/..., just not as bad as this one. (Compiz currently uses 1400 MB on my system, but it has been running for almost a week.)

Compiz using 6GB to day.

I have to log out and back in.

[tsaitgaist (kevredon)]

until the bug is fixed, there is an easy workaround.
when compiz take too much memory, you only need to restart it, logout is not required.
run the command "compiz --replace" (using alt+f2 to not stop it).
If unity becomes buggy after that, do the same : "unity --replace"

[SilverWave (silverwave)]

Looking at similar bugs and the advice given I have decided to uninstall indicator-multiload.

Although not the cause of the underlying issue, it does seem to exacerbate the problem.

[Patrick Krecker (pkrecker)]

Want to note that running in classic mode, Compiz has 37 megs resident in memory. When running Unity, Compiz starts out using 150megs and begins climbing consistently. Reaches 1.5 gigs after about two hours. After 24 hrs, my 8 gigs of ram are 100% consumed and my machine is too busy swapping to be responsive.

Dual screen.

This has resolved the issue for me.

Still an issue as of today on afully updated compiz and unity.
