1502803 - Potential memory leak after browsing some websites, related to audiodg

Status: RESOLVED INVALID

(Core :: DOM: Core & HTML, defect, P3)

Description

[Maximilian Kohler]

Attachment: memory-report.json.gz

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0

Steps to reproduce:

2 gmail tabs, 2 reddit tabs, 1 craigslist tab. Had watched and closed a twitch tab and youtube tab more than 15 minutes prior. 
 
"Free memory" - GC, CC, minimize memory usage, all had no impact. 

FF 63.0 64bit. Win 8.1 x64. 8gig ram. 

Can't upload screenshots here so I'll just describe:

* With 1 window and 4 tabs the task manager shows firefox at 22% CPU and 2,123.3MB (74% total). 

* After closing FF I get 1% CPU, 25% memory. 

* Reopen, tabs not loaded: 1% cpu, 33% memory. 

* Load all 4 tabs, sign in, etc.: 1% cpu, 48% memory. 




Actual results:

Basically seems to be a bug where memory and cpu aren't released after they're not in use anymore. 


Expected results:

Basically, 15 minutes after having 4 tabs idle firefox was reading:

22% CPU and 2,123.3MB (74% total). 

when it should have been: 

1% cpu, 48% memory.

The memory report has ghost windows in it. Do those appear just after loading this set of tabs, or only after some time?

I'm not sure if that's the entire explanation of what's going on here - maybe :mccr8 can help triage this further, I'm not an expert on tracking these down, but it's likely we'll need more detailed steps to reproduce the problem.

Comment 4

[Andrew McCreight [:mccr8]]

What websites are the ghost window from? From a fresh session, if you load those pages, use them like you normal would, then close them and wait a few minutes, do you get ghost windows again?

Comment 5

[Andrew McCreight [:mccr8]]

If you can reproduce it, you could see if you can still reproduce it without addons enabled. You have a few YouTube related addons. Maybe one of those is somehow triggering the leak.

Not sure what is addressed to me, but I don't know anything about ghost windows. Maybe they are related to the Sync Tab Groups addon, or maybe that is what the memory leak is - instead of closing stuff it shows as ghost?

Iridium for YouTube addon has already been disabled for a while. I tried monitoring memory usage while using the browser, watching videos, using Video Speed Controller to change video speeds, and I haven't been able to find a particular cause. It happens very gradually. The leak does not require me to open a new set of windows with the Sync Tab Groups addon, or use that addon in any way. 

Current memory usage after some hours: idling around 60% and ~1300MB for the top process. Hadn't opened any Twitch tabs.

25% closed. 35% after opening. 45% after loading 1 gmail tab. 47% after loading a 2nd gmail tab. 50% temporarily after fully loading everything. 
Now the top process is 900MB and 47% total. Opened youtube tab. Still under 50%.

So ~10% memory gets lost in a few hours but it's so gradual I can't pin it to one thing.

The "Facebook container" addon by Mozilla might be a contributor. I noticed that the usage went up about 5-6% after loading and closing some FB tabs from my gmail notifications, and the usage wasn't reset after.

Comment 8

[Maximilian Kohler]

Ok, think I figured out something useful. There seems to be a leak related to audiodg.exe service and balabolka. 

I use Balabolka to read text to me from firefox and/or while firefox is open. I notice that audiodg.exe gradually eats up memory while doing this, and the firefox process does as well, at the same time. 

I can use this .bat file to reset audiodg:

net stop audiosrv
net start audiosrv

But after doing so, the firefox process still hangs on to the extra memory it ate up. 



Also, I noticed a recent update to the facebook container addon, and not sure if anything significant was changed, but I didn't notice any lost memory when using it.

Maximilian, can you still reproduce this?

Comment 10

[Maximilian Kohler]

I built a new PC with double the RAM (16 Gig) and haven't noticed any issues. Looking right now I have 10GB in use, 5.4 available, 5.3 cached. 770MB paged pool, 615MB non-paged. 25/29 GB committed. 10+ firefox processes totaling around 4,000 MB. Showing 66% memory use on processes tab.

Looking at my previous messages it seems Balabolka may have been implicated, and I haven't used that program in a long time. So I tested it out.

I left Balabolka on overnight and now the memory use is at 77% vs 66%. Firefox is using 12 different processes and about 4,800 MB. Balabolka had finished reading the book when I got to it. When I closed it the memory usage started slowly decreasing into the 60's (then went back up to around 77% when I activated a browser-based game in Chrome).

Windows Audio Device Graph Isolation is 4th highest mem usage at 656 MB.

Memory performance tab is about the same for non-paged pool and paged pool. Cached went down to 3.6, available down to 3.6. In use up to 12.3. Committed up to 29/33.

Chrome is on 13 processes and about 1200 MB. I started playing a browser-based game in Chrome and it raised to 1900 MB.

Now that I think of it, perhaps the leak is more of an audio device leak rather than Firefox, and perhaps Firefox just uses significantly more memory than Chrome by default. But then I recall the memory being freed up by closing my browser. I'll do that and report back.

Well, before I could close Firefox, the browser-based Chrome game caused Chrome to freeze up temporarily, and the game had to be refreshed, and that seemed to reset all the memory statuses to what they were last night. Firefox dropped even lower to about 3,500 MB (down from 4,800 without changing anything in Firefox). Total mem usage is 65% (with the Chrome game active). Windows Audio Device Graph Isolation is nowhere near the top. Chrome is still around 1800 with the game active.

So sounds like not a Firefox bug. Thanks for the info
