Memory Leak with Flash Game - video of incident - Fix?

My hypothesis:
There is a memory leak in Flash Player that leads to Flash crashing, predictably and repeatedly, when used.
My question:
When will this problem be fixed?
Evidence:
Observe the progression in the following single-take video of me playing my favorite Flash game, posted to Youtube. Skip to the times indicated in the "About" description for the video to observe the increase in use of physical memory, as observed in Windows Task Manager, until there isn't anything left.
http://www.youtube.com/watch?v=gNIJvTuUitU
My computer gets bogged down, the game stalls out, and Flash needs to be closed to enable my computer to function once more. It makes it impossible to play this specific game for very long, and is an insidious problem lurking in the background every time I watch a video, play a game, or use Flash Player for any purpose. My computer always slows down, with the problem worsening as time passes until I need to close everything and start again.
Details:
Flash Player Version: 11.7.700.224
Operating System: Windows Vista (32-bit)
Browser: Mozilla Firefox
(Also happens when using Google Chrome)
Conclusion:
If you need further information about my specific computer, please feel free to ask.
If this problem is specific to my computer, I would appreciate knowing this and determining a way to solve the problem. My suspicion is that the problem originates in Flash Player itself and is experienced by many people in a variety of circumstances. It is my hope that an articulate response indicating how long it will take to correct this bug in Flash Player can be provided.
Thanks in advance for your help.

Memory leak in Flash with Win7, IE9, 64bit

I have been having an issue for quite some time on 2 different computers. Both of them are Windows 7 64bit and use IE9.
Generally I have 1 - 5 tabs open in IE at any given time. Usually one of them is a tab for Yahoo Mail. Other tabs are related to whatever I may be searching for or doing at that time, so pretty varied. Throughout the day at random times I will begin to get a grey icon for anywhere on some tabs where there is supposed to be a flash video (like the ad in the right side of the Yahoo Mail tab)... When it happens I can open Task Manager in windows and I notice that 1 or two "iexplore.exe *32" processes have memory consumed in excess of 600,000K. When I end those processes I am again able to see any flash videos that need to be viewed.
If I leave Task Manager open throughout the day I can see the memory consumption increase on various tabs until I cannot see any more flash videos or even open new tabs in IE until I end those processes. Further, the memory does not get released if I just close the tabs in IE, but I must either end the specific process or close all tabs in IE so that IE is completely unloaded.
I have since uninstalled the Flash player and the issue has gone away. I can re-install the flash player and the issue returns. Can you please help? This has been a huge annoyance and I had hoped that it would be fixed sooner or later. Unfortunately it has not been fixed and has finally prompted me to post something....

First, I just wanted to follow up on this thread and let you guys know that we'll continue to look into it. I also want to clarify some player behavior, and provide tips for helping to identify a defect that we can take action on.
Whenever you refresh/reload a tab, the browser should signal to us that our process is being destroyed, at which point we would release all of our resources and shut down. SergeStone's comment above makes it sound like this might not be happening in a particular case. I'm going to build out a few tests this week to explore this in more detail, and I'll follow up with results.
Also, it's worth discussing the difference between memory consumption and memory leaks. Flash Player is designed to consume a percentage of your available memory. If you have a 32-bit machine with 2GB of RAM, we're going to consume a lot less memory than a 64-bit system with 16GB of RAM.
Not all Flash content is authored well. If the ActionScript developer is continuously loading objects into their SWF and never releasing them (a slide-show is a good simplistic example), you'll see a steady usage increase as each new object loads in. You should also see that evenutally, our automatic Garbage Collection process will kick in. Memory will peak out, and then you'll see a short CPU spike as we look at all of the available objects and cull as many unused ones as possible, consumed memory will dip down significantly (as long as we can cull stuff), and then start growing again until the next time GC kicks in. We tend to do this judiciously, as poorly-timed GC can cause games to stutter if it happens when lots of things are moving around on the display and you don't have a lot of available CPU.
If it's our bug, it should be straightforward to fix, and I can follow up to this thread with a beta build for you guys to evaluate once we have one available. In the meantime, it would be interesting to know if you're seeing the problem on our current Beta builds (which is where we would do the work).
Here's a link to the latest Beta download:
http://labs.adobe.com/downloads/flashplayer11-5.html
Also, the simplest example is the most actionable. If you can find a situation where a site in a single tab reproduces the problem, that's a quick and easy thing to deal with. If the repro case involves opening seven tabs and waiting six hours, someone needs to repeat that over and over, until they can isolate what content experiences the problem and then iterate a bunch more with a debugger attached to try and isolate the root cause. The more complicated the content, the more difficult that is.
Secondly, I wanted to offer some actionable suggestions that you could use now to work around this issue.
Try Firefox or Chrome. Both of these browsers run Flash Player as a separate process.
For those of you using Performance Monitor and other tools to measure, you can directly observe the resources used by Flash Player
For the folks concerned about Bookmarks synchronization, both Firefox and Chrome provide native bookmark syncing and import from IE mechanisms.
Xmarks is a really nice, free utility that provides cross-browser, cross-platform bookmark synchronization.

FireFox with adobe flash using a retina macbook pro under win 8.1 64 bit is lagging . when you move the mouse above any flash game / video

Hi
I asked this question again and i reported this bug , i am a computer engineer and i tested it with few macbook pro retina laptops , when u use win 8.1 64 bit or 32 bit and install adobe flash under firefox try to play any game in facebook , view video on youtube or use any FLASH video and move the mouse above the screen of the flash game / video / etc , the screen will lag alot .
under chrome this problem doesnt exist but the screen is blurry in chrome when using retina screen thats why firefox is better , but the problem is annoying .
i tried to disable hardware acceleration as you suggested still the same problem

Hi thesoulkeeper,
Do you have the bug number? We can try needsinfo to ask for some help.

Memory Leak with GotoAndStop()

I am trying to track down a solution to a memory leak within an embedded video. If I embed a video on the timeline and then run gotoAndStop or gotoAndPlay to a specific frame every time the frame changes it takes in more memory until it crashes at about 1.7GB however if I run a straight play() on the same clip the memory usage remains constant. I have also tried System.gc() as it is an AIR App and have tried unloadAndStop() with the embeded video being loaded into a Loader and neither can reclaim any memory.
I am looking for a a way to resolve the memory leak or another way to be able to rapidly jump to specific frames of video as far as I know this is not possible with external flvs.
Thanks
Dave

video is much like a .gif file. if you start at frame 0 and jump to frame 30 it needs to redraw what it does nt have in frame 30 which means tellign it to start at frame 30 is the same as telling it to get all information from when it last changed which might be frame 27 to complete the frame of what should display on frame 30.
this is why its slow to play backwards. and best to play an flv forward.
what i would suggest if you do not need video persay, would be to use png sequences. but if your videos are long then i suppose it would be a greater advantage to keep it compressed.
what is the quality as well of the video and its size and your frame rate?
You mention that you are creating a 3d view, how is that? do you use more than 1 swf ?
I still think this does not sound like a play head issue, since the video is already compiled.

Memory leaks with Third party classes

Hello all,
This is fairly known problem. But I guess, my problem gives a new dimention to the problem.
I have an application which is developed by me. This application ideally needed to use third party classes ( obviously no source code is supplied ). These third party classes provide extra functionality required.
The problem is, when I don't use third party classes in my application, every thing is fine. When I include third party classes, I am having memory leaks.
Then I tried to investigate memory leaks with Optimizeit tool. It is new to me. As of now, I understood, we can identify where the memory leaks are occuring.
finally the problem is, in order to solve this, I need some patches in the code. But I don't have source code for those classes. How to solve this problem?
For example,
I use a third party classes in my code like this,
ThirdPartyMemoryLeakClass obj = new ThirdPartyMemoryLeakClass();
This 'obj' is made static, as it takes lot of time to create this object. Obviously this object contains several references to other objects, which I can't control.
In the process of reusing this object, I am getting memory leaks.
Any ideas regarding, how one has to deal this type of situations? What are the issues involved with this case? Are there any similar problems, which have been solved? are most welcome.
many thanks for your time.
Madhav

Decompile it using jad. Find leak.Yes, I too got the idea and tried to decompile those classes and recompile. I had some problems while recompiling. Is this is the only way to get rid of this problem?
I was refering to powersoft.datawindow.DataStore class. Does any body here has worked on these?
Can you suggest me how to find the memory leak causes? if you were needed to find out memory leak causes, what would be your approach?

Memory leak with swf generated by Xcelsius 4.5?

Hello,
I've experienced some memory problems with swf generated with Xcelsius 4.5. I'm using Windows Vista and Internet Explorer 7.
I noticed that every time I refresh my dashboard using the F5 key, the memory used by the Internet Explorer process increases (or doubles).So, in case I need to refresh my dashboard many times, the memory used by the browser becomes definitely too much and compromises my system stability.
Does anyone have experienced this problem? Is this a memory leak? Is there a way to fix this problem?
Thank you,

That's the trick who does it, thank you!

Memory leak with 1.6.0_07 in applet using Swing

Java Plug-in 1.6.0_07
Using JRE version 1.6.0_07 Java HotSpot(TM) Client VM
Windows XP - SP2
I have a commercial application that has developed a memory leak with the introduction of the latest plugin. The applets chew up memory and eventually freeze. They did not before. Using jvisualm I see a build up of native arrays, primarily int[][] and char[]. I'm still investigating. Anyone have a similar experience?
The Applet uses a swing interface, uses buffered images and swing timers, and regularly performs http connections to the server which result in actions via the SwingUtil.invokeLater() method.

I am Using Internet Explorer Browser Version 6.0.Huge security hole.
Its not throwing Error / Exception Wrap a try/catch at the highest level possible.
Catch 'Throwable'. And log/display it somewhere.

Memory Leak with JPopupMenu

It seems there is a memory leak with JPopupMenu. The following program demonstrates this leak. If you run the program, click on show form, and then close the form, the used memory will be GCd appropriately. If you click on show form, then right click on the table to show the popup (even if you dont do anything else with the popup) then close the form, it never GCs the form. I've tried all kinds of crazy things, but I cant seem to find what is keeping the memory from being GCd.

BTW instead of continually printing out the memory use a profiler (jvisualvm in the jdk/bin directory -> heapdump -> search on your class -> view in instances -> find nearest GC root).
Looks like BasicPopupMenuUI doesn't remove a reference to the JRootPane immediately. As far as I can see it will be removed when another menu shows.
As a hackish workaround you can try this in you FrmReferrals#uninit():
            for(ChangeListener listener : MenuSelectionManager.defaultManager().getChangeListeners()) {
                if (listener.getClass().getName().contains("MenuKeyboardHelper")) {
                    try {
                        Field field = listener.getClass().getDeclaredField("menuInputMap");
                        field.setAccessible(true);
                        field.set(listener, null);
                    } catch (Exception e) {
                        // ignored
                    break;
            }Funnily enough though it isn't there when I reduce your code to a SSCCE:

Evony Memory Leak in Flash Player

Is there a work-around of any sort for the massive memory leak in the Evony flash player based game? When you play this game actively, opening dialogs, and submitting attack, the game can easily leak 250MB/hour until the browser grows in size to well over 1GB, before either crashing or becoming unacceptably slow to interact with.
This problem is well known on the Evony forums and easily verified by numerous people. Just google "Evony memory leak".
It has been repro'ed on all browsers and all platforms that have the Adobe Flash player. Is this being investigated? Does the dev team know about this problem? Is there already a thread on it here somewhere that I missed?
Thanks,

[Bug?] X-Control Memory Leak with Large Data Array

[LV2009]
[Cross-posted to LAVA]
I have found that if I pass a large data array (~4MB in this example) into an X-Control, it causes massive memory allocations (1 GB+).
Is this a known issue?
The X-Control in the video was created, then the Data.ctl was changed to 2D Array - it has not been edited in any other way.
I also compare the allocations to that of a native 2D Array (which is only ~4MB).
Note: I jiggled the Windows Task Manager about so that JING would update correctly, its a bit slow, but it essentially just keeps rolling up and doesn't stop.
Demo code attached.

X Control Bug [LV2009].zip ‏42 KB

Hi Jon (cool name)
Thank you very much for your reply. We came to this conclusion in the cross post and it is good to have it confirmed by LabVIEW R&D. Your response is also similar to that of my AE which I got this morning as well - see below:
Note: Your reference number is included in the Subject field of this
message. It is very important that you do not remove or modify this
reference number, or your message may be returned to you.
Hi Jon,
You probably found some information from the forum. The US engineer has gotten back and he said that unfortunately that's expected behaviour after they have conducted some tests and this is what he replied:
"X Controls in the background use events structures. In particular the Data Change Event is called when the value of the XControl changes (writing to the terminal, local variable, or value change property). What is happening in this case is the XControl is getting called to fast with a large set of data that the event structure is queuing the events and data that a memory leak is produced. It is, unfortunately, expect behavior. The main work around for the customer in this case is not call the XControl as often. Another possibility is to use the Synchronous Display Property to defer updates to the Xcontrol, this might slow down a leak."
He would also like to know if you can provide with more details how you are using the Xcontrol, perhaps there is a better way. Please refer to the link below for synchronous display. Thank you.
http://zone.ni.com/reference/en-XX/help/371361G-01/lvprop/control_synchronous_display/
In my application I updated the X-Control @ 1Hz and it allocated at MBs/s up to 1+GB before it crashed, all within a few hours. That is why I called it a leak. I am really worried that if this CAR gets killed, there will still be an issue lingering that makes using X-Controls a major problem under the above conditions. I have had to pull two sets of libraries from my code because of this - when they got replaced with native LabVIEW controls the leak when away (but I lost reuse and encapsulation etc...).
Anyways, I really want to use X-Control tho (now and in the future) as I like all other aspect of them. If you do not consider this a leak, can a different #CAR be raised that may modify the existing behavior? I offer the suggestion (in the cross-post) that the data be ignored rather than queued? Similar to Christian's idea, but for X-Controls. Maybe as an option?
I look forward to discussing this with you further.

Problem Report: Severe memory leak in Flash Player 9.0

Summary
Flash player 9.0 is prone to a severe memory leak when
playing SWF files produced by Captivate 1 containing full-motion
recordings.
Versions affected
The problem reproduces with Flash player 9.0 (Flash9.ocx,
Version 9.0.16.0) hosted in either Internet Explorer 6.0 or Mozilla
Firefox 1.5 on a Windows XP SP2 system.
The problem does not reproduce with Flash player 8.0
(Flash8.ocx, Version 8.0.22.0) in the same environment.
Description
After a few minutes playing a SWF file produced by Captivate
1 containing a full-motion recording recorded with Captivate 1, the
host browser ends up using more than a gigabyte of memory, and the
playback of the movie slows down to a halt, together with
responsiveness of the whole system.
Impact
Our organization develops E-learning content with Captivate 1
for various customers, mostly Fortune 100 companies.
This bug severely limits our ability to deliver content to
our customers.
Steps to reproduce
1. Using Captivate 1.01.1418, create a “blank
movie” with default settings.
2. Use the “Record” button and begin recording a
full-motion movie for about 2-4 minutes. For the purposes of this
bug, it is enough to record a user typing random text in a Notepad
window resized to fit in the default 800x600 window.
3. After recording the full-motion movie, publish the
Captivate movie as a “Flash (SWF)” movie, using default
settings (making sure that the “export HTML” checkbox
is selected).
4. Open the published movie’s HTML file with a host
browser, making sure that the browser is using the Flash 9.0
player.
5. While the movie is playing, watch the memory usage of the
browser process using Windows Task Manager, and you will see that
the values of the “Mem Usage” and “VM Size”
counters keep increasing until the system becomes unusable.

FLVPlayback Memory Leak in Flash CS3

Hi There,
I' making a flash file with AS2 in Flash CS3. I put a FlVPlayback in stage and let it load a couple of FLV files from my local HDD and playing continuously. I use "addEventListener" to check the current running flash movie is completed. After complete event occur, I load another flv movie to paly again.Here, I noticed that memory usage is increasing every time a new flv file is loaded and played. I heard "addEventListener" in CS3 is causing the memory leak and not being detected by GC.
Please let me know if there is a solution to solve the memory leak issue. I posted my codes here to know something I'm doing wrong.
Thanks in advance...
================================
onClipEvent (load)
    function _fun_complete(eventObj)
        this.autoRewind = "true";
        var _v1 = _root.v;
        var _v2 = _root.FLVlists.length;
        --__v2;
        if (_v1 < _v2)
            ++_v1;
        else
            _v1 = 0;
        this.contentPath = _root.FLVlists[_v1].path;
        var _v3 = _root.listVids[_v1].width;
        var _v4 = (stage._width - _v3) / 2;
        this._x = _v4;
        _root.v = _v1;
        this.play();
    this.addEventListener("complete", _fun_complete);

Helllo Friend,
Thanks for your feedback. The problem with removeEventListener is that , the player stops and not playing anymore. In my application, I nned to loop and play one FLV files after another. For example, I need to play 3 flv files, File1.flv, File2.flv, File3.flv. I load and play File1.flv first. Once complete event trigger from "addEventlisterner" , then I load File2.flv and then File3.flv and then Flie1.flv. So it needs play continuously and causing memory leak. Please let me know if there is another way of working around.
Regards

Still memory leaks with 10.8.4

I hoped 10.8.4 could solve the issue..
Unfortunately I still have memory leaks, pages out and inactive memory full for a lot of programs running. First of all FCX importing and transcoding full the inactive memory, and OSX slows down, swapping to the SSD. The same problem with all (4 in total) macs mounting ML.
Has anyone solved the problem please?
Thanks in advance.
Attilio

Attilio, although I'm not a Final Cut user, I suspect that your problem is, as Kappy first said - insufficient RAM.
See: http://forums.macrumors.com/showthread.php?t=1332888 for instance.
It's a RAM hog. With the Retina, you're stuck with the RAM you've got now, unfortunately. With any other hardware, I'd consider boosting the RAM as much as you can. I don't run FCX or any video editing software (I build web sites - so I use Dreamweaver, Photoshop, Lightroom etc.) and I boosted the RAM in my Mac Pro to 18GB quite a while ago because I was seeing a lot of pageouts and slowdowns with 10GB. I do tend to have a ton of windows and apps open at once.
See also: https://discussions.apple.com/thread/4759586?start=0&tstart=0 - Kappy's very good explanation of memory usage and various links to check.
Whether it appeared to run better in SL or not, I can't really say - unless you ran two identical Macs, side by side doing exactly the same things in FCX with the two operating systems installed, I don't know how one could accurately assess that.

Memory Leak with new Font()

Hello all,
Not sure if this is the right place to post this but here goes. I have a program that needs to change the font of at least 250,000 letters, however after doing this the program runs slow and laggy as if changing the fonts of each letter took up memory and never released it? Here is a compilable example, Click the button at the bottom of the window and watch the letter it is currently working on. You will notice that around 200,000 it will begin to not smoothly count up anymore but count in kind of a skipping pattern. This seems to get worse the more you do it and seems to indicate to me that something is using memory and not releasing it. I'm not sure why replacing a letter's font with a new font would cause more memory to be taken up I would think if I was doing it properly it would simply replace the old font with the new one not taking anymore memory then it did before. Here is the example: This program sometimes locks up so be prepared. If someone could maybe point out what is causing this to take up more memory after changing the fonts that would be great and hopefully find a solution :) Thanks in advance.

You're creating a quarter million distinct Font objects, and obviously you must be hanging on to all of them because each character is having its font set to the newly created object. So if you have 250k chars, you're forcing it to have 250k Font objects.
Since the only difference is that rand.nextInt(50) parameter, just pre-create 50 Font objects with 0..49, stick 'em in the corresponding elements in an array, and use rand.nextInt to select the Font object to use.That does make sense but it does that when the the program is first launched and doesn't lag. But the second and third time you change the letters font it seems to lag so if it wasn't taking up more memory the second time it should perform like it did when it first launched. I don't care to investigate any further. The real problem is almost certainly the quarter million Font objects. It could be that 250k is fine, but by the time you get to 500k, it has to do a lot of GC, and that's where the slow down is coming. You might even be able to make it work better with the code you have just by tweaking the GC parameters at startup, but I wouldn't bother. Fix the code first, and then see if you have issues.
Does creating a new font for each of those letters not replace the old font object? If it didn't use more memory the second and third time I don't think you would see the skipping in the counter and the slowing down of the iterations. So it must be remembering some of the old font objects or am I wrong?Using new always creates a new object. When you do it the second time around, and call letter.setFont(newFont), the old Font object is eligible for GC. That doesn't mean it will be GCed right away though. The JVM can leave them all laying around until it runs out of memory, and then GC some or all of them.
