804787 - firefox memory usage explodes on www.morethanamap.com/demos/

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[thierry.vignaud]

User Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:19.0) Gecko/19.0 Firefox/19.0
Build ID: 20121023030553

Steps to reproduce:

I visited http://www.morethanamap.com/
I then clicked on the "view demo" link when "Data Visualization" is displayed.
I then selected "earthquakes"
(http://www.morethanamap.com/demos/visualization/earthquakes)
Then "population" (http://www.morethanamap.com/demos/visualization/population) once it was completed.
As the population demo goes on, firefox memory usage went from ~300Mo up to 1.8Go at which time I had to desperately kill some the firefox process in order to maintain my system usable.

This with firefox nightly, on Linux x86_64 (Mageia Cauldron) with mesa-9.0 on a Radeon X1650 PRO video card using the radeon free driver.


Actual results:

Firefox (nightly) eats all memory, making the system slow (swap storm until I killed firefox)


Expected results:

Firefox should have maintain using some reasonable amount of memory

Could you please copy the output of "about:memory?verbose" and paste it into an attachment to this bug?

Followed your steps with Ubuntu, I had a maximum of 500 MB while the population demo was running, but it quickly went down to normal values (100 something) after 2-3 seconds.

This sounds like it could be a driver bug.  Can you re-test with

  layers.acceleration.disabled

set to true in about:config?  (At least, I think that's the right pref.)

Yeah, this really smells like hwaccel problems.

Comment 4

[thierry.vignaud]

That doesn't change anything.
For the record, I'm using noscripts, adblock plus, firebug, greasemonkey, session manager
as well as two dictionnary extensions:
- Dictionnaire francais
- Difazier an drouizig

Attachment: about:memory?verbose (showing it's JS objects that eat memory...)

Comment 6

[Andrew McCreight [:mccr8]]

Specifically, there's over a gig of elements, which seems unusual. Perhaps the fault is JS and not graphics...

Comment 7

[Justin Lebar (not reading bugmail)]

Would you mind trying in safe mode?  Sometimes add-ons do dumb things, and this doesn't sound like the type of add-on leak that we've prevented wholesale (bug 695480).

I also couldn't reproduce on 64-bit Ubuntu.  The fact that it's JS array elements makes me now think that it's probably due to an add-on.  Restarting in safe mode (see comment 7) temporarily disables add-ons, so if that fixes the problem we know it's an add-on.  After that, it's a matter of selectively disabling add-ons and trying again to reproduce.  My bet would be on a GreaseMonkey script causing the problem, but I could be wrong.

[Justin Lebar (not reading bugmail)]

This has been sitting for a long time, so I'm going to close it.  Thierry, if you have time to answer our questions, please re-open this bug and we'd be happy to investigate further.

Actually as of ff-22b1, the issue is fixed.
