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.

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

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,

Memory leak in AudioServicesCreateSystemSoundID with sound files

hi !
Instruments indicates a 64Ko memory leak in "AudioServicesCreateSystemSoundID" when I use a sound that I have created with GBand / iTunes. When I use the sound file "tap.aif" from the "sysSound" sample, there is no memory leak.
What's wrong with my audio file ?
It's a AIFF file, 95Ko, 8 bit mono 22Khz @ 176kbps.
thanks...

appFile = [ [ NSBundle mainBundle ] pathForResource : _filename ofType : _extension ];
FileUrl = [ NSURL fileURLWithPath: appFile ];
if ( AudioServicesCreateSystemSoundID( ( CFURLRef ) FileUrl, &soundID ) != kAudioServicesNoError )
return false;
I don't think the code is wrong because when I change the name of the sound in '_filename', there is no leak.
I haven't found in the documentation the audio file properties ( 8/16 bits, ... ) supported by 'AudioServicesCreateSystemSoundID'.
The code is for iPhone.

PGA memory Leak issue along with TNS: listener could not hand off client connection

Hi,
We have two Oracle Database instances in a 32 bit Standard Edition Windows OS machine with 3 GB RAM : 1) 1525 MB (SGA+PGA) 2) 515 MB (SGA+PGA)
Recently we upgraded the RAM from 3 GB to 4 GB. Subsequently we upgraded the SGA + PGA of the 2nd instance to 771 MB.
This has resulted into PGA memory leak issue reported in the alert log file and trace file.
Reverting back the SGA+PGA size to 515 MB solved the issue.
Is this issue related to Address Windowing Extension (AWE)?
Is the reason related to Total memory for all the cumulative Oracle instance should be < 2GB.
How to solve this?

There may be something fixed in the patch that gives the error rather than mysterious hangs. I would prefer that, myself. There may be something in the patch that changes how Oracle allocates user, system and program areas.
At some point you spend more trying to limp things along in a growing environment than simply upgrading. 32 bit environments these days is an indicator that management is figuring some false economies. But that's their prerogative.
The PGA can be affected by many things, not least of which is how the application uses it. Much has been written about it, my own experience has been more is used than most people say. But that is probably just my app. Note there are different ways to set it, and a parameter with "target" in it might not be a hard limit. Different execution plans for the same code may use different amounts of memory - there can even be situations where forcing some code to use a sort area instead, or even forcing more operations to disk, can free up more pga for everyone else. It depends. But that's why I look at multi-pass operations in dbconsole.

Memory leak in OracleDataReader with UDT in 11g

Hi,
Can someone confirm that the following code is leaking (hugely!):
command = new OracleCommand("select c.polygon from spatial c", connection);
reader = command.ExecuteReader();
while (reader.Read())
reader.Dispose();
command.Dispose();
where polygon is SDO_GEOMETRY.
Memory consumption for this code in Task Manager is +100MB above "normal" and it does not drop after calling Dispose() methods. I've also noticed that this "leak" is proportional to FetchSize. GC.Collect also does not change anything.
Is it a bug of 11g beta or am I missing something?

I'm not sure what do you mean by ODAC 2007. I couldn't find anything useful on your website regarding "ODAC 2007". I'm using Oracle 11g ODAC 11.1.0.5.10 Beta and I'm particularly interested in SDO objects. Based on your code samples I created strongly-typed C# classes for SDO objects and everything works like a dream (apart from this memory leak). And the performance is just OUTSTANDING! Keep up the good work!
BTW: Congratulations regarding ODP.NET API for binding UDT with C# classes. It's very intuitive and easy to use even if you want to create C# classes from the scratch, i.e. without any wizards. Did I mention performance? :-)
Many thanks Kiminari for your reassurance: it means a lot to me since I can now keep working on my project without any worries (I need a stable version of ODP.NET with UDT before Q2 2008). I was thinking about using OLE DB but the performance was horrible due to marshalling, passing untyped objects, etc. But you've just saved the day, and for development purposes the leaking version is absolutely fine.
Just small questions: when can we expect "ODAC 2007" or at least another beta? More less? Any estimations?

Memory leak in WebView with custom UserAgent

Hi,
When I use the method with using NavigateWithHttpRequestMessage to modify my UA, I cannot dispose my webview properly - there seems to be a memory leak when calling this.
In my code when I comment out the following line:
myWebView.NavigateWithHttpRequestMessage(httpRequest);
The memory leak goes away.
Please note this seems to be a WP8.1 issue only, the memory leak does not appear on Windows.
Is this a known issue? Is there a work around here?

Hi Justin,
Could you share a reproducible sample with us for a test purpose?
What kind of other information include in your httpRequest, let's say if we exclude the UserAgent information, will the memory not release issue happens again, I'm not sure if the issue happens on setting UserAgent or on NavigateWithHttpRequestMessage
part.

Memory Leak Java Plugin with Swing Applet

Hi
I experience the following problem and desperately need help on this. The Java Plugin (I use Version 1.3.1_02) seems to have a problem in printing Swing Applets.
The problem can easily be reproduced (at least with NT):
1) Start Internet Explorer or Netscape (I used 5.5/4.07)
2) Launch the following demo swing applet
http://java.sun.com/products/plugin/1.3.1_01a/demos/jfc/SwingSet2/SwingSet2Plugin.html
3) Print the applet and observe (using task manager) the memory used by the browser process (the memory used by the process will increase every time you hit the print button but never decrease unless you shut down the browser)
4) Print a couple of times (you may want to pause your print queue) and you will be able to crash your computer
This seems to be the same bug reported with 4638742. However it says "in progress" for quite some time and I was wondering if some genious might know a work around for this.
Cheers

Firefox 21.0 on OS X 10.8.4 still has a memory leak that occurs with no Add ons, 1 tab and leads to 3GB of memory usage in 10 minutes.

While using Firefox 21.0 on OS X 10.8.4 with 4GB RAM, Firefox memory usage marches up and up until at 3GB (on my iMac) Firefox hangs and is 100% non-responsive and must be killed with Force Quit. It takes 10 minutes to occur.
No Add Ons
One tab

John99,
Unfortunately, the problem was WORSE in FF 22.0. I regressed to FF21.0 and shut off automatic updates. I may even go back to FF3.6, which is the last one where I didn't see this problem.
Thank you for trying but as a longstanding developer I know that pervasive memory leaks is a sign of a broken development process. Thank you for trying...

I think I found a memory leak in Flash 10.1 involving a particular page

Go to [url]http://politicalticker.blogs.cnn.com/?fbid=o9Nb8jC6wvV[/url] and the browser keeps gobbling up memory until an eventual freeze and crash. I get this result using IE8 in conjunction with flash version 10.1.51.45.

I have experienced something similar, and went on quite an investigation over the past 3 days to work out the cause of the problem. However, it simply appears to be the new more "efficient" way the garbage collector in 10.1 works.
During execution, my app might use 400mb, then release it. In 10.0 and earlier versions, that 400mb would be reclaimed by the player pretty much straight away. However, now it seems to decide that if you have declared you want to use 400mb of RAM yourself, then it decides that for a while it will become a sort of new temporary upper limit for garbage collection. Thus, it's entirely possible to see memory use climb and climb seemingly unchecked. I guess now they are working on the idea that if you declared that much RAM can be used by your app at one point, they might as well let it fill up and keep those gc() operations to a minimum. What's if you then have 400mb of garbage that needs to be cleaned out and you suddenly decide that hey - you want to actually use 400mb yourself? Well, thankfully it seems that garbage collection runs and then your 400mb is provided.
Interestingly, system.gc() appears to not work anymore.

Memory leak in dll with an imaq-function

Hi,
I am currently writing a dll which uses the imaqImageToArray function.
Of course this function allocates new memory every time it converts a picture, and as I convert 180 pics a second and the Program shopuld run for hours that is quite a problem for me.
The solution should of course be the function free(void* MyPointer). And if I use malloc to allocate some random memory, instead of the imaqImageToArray, this works perfectly.
However when I call free() to release memory allocated by the imaqImageToArray function, the dll/LabView-Program will crash.
So I wonder what function the imaq-Functions use to allocate memory and how I can get rid of it again. Is there another imaq-function?
Thanks already!
Greetings
Solved!
Go to Solution.

Hi,
sorry for the misunderstanding. I use the imaqImageToArray function inside the .dll. The Code Hence is a c-code.
#include "extcode.h"
#include "nivision.h"
... some stuff/the dll-function etc....
uint8_t *Pointer;
Pointer = (uint8_t)imaqImageToArray(MyImage,MyRect,&Rows,&Columns);
if(Pointer!= NULL)
     free(Pointer);
... other stuff
Sadly I can't find a detailed description of the function. I assume the void* Pointer returned by imaqImageToArray points to an Array, however I am not sure wether it points to a usual c-array or a LabView Array, meaning:
typedef struct {
    int32_t dimSize;
    double Element[1];
    } LVArray;
That would explain why free(); won't work.
I think I got a step further though, as I found a function in the "extcode.h" called    DSDisposePtr(void *p). That should be the equivalent to free() for LabView Datastructures.
However even though I have included everything from the cintools directory explicitly to the project, the Linker complains about a not found externic object. Anyone knows which .lib files I need to include where to be able to use that function?
Thanks

Best Practice: Working with Win7 32Bit & 64Bit Versions in MDT 2012

Whats the recommended way for producing bootable media using MDT2012 that would support 32 and 64 bit versions of Windows 7?
Should I have 2 deployment shares or do I import the 2 operating systems source dvd's into the same deployment share?
is it possible to create 32 & 64Bit bootable media from 1 deployment share and if so what settings would I need to modify in the task sequence & advanced configs to allow me to do so?

No problemt to run both x86 and x64 in the same deploymentshare.
Yes you can create both 32 and 64 bits boot media (winpe) in one deployment share.
In the properties of you deploymentshare, general tab you choose if you want to support both x86 & x64.

Memory leak and problem with polymorh vi when calling vi from dll

Two problems appear for me when using the setup below.
First, I have a vi for opening a secondary vi:
Then I have a vi for calling the opened, secondary vi:
These two are compiled to a dll. The first one is called once, calling a function "open(char *)". The second one is called over and over, calling a function nextevent(double *, int). A simple example of an opened, secondary vi looks like this:
The code used to send data looks approximately like this:
dataout = malloc(dx->numelems * sizeof(double));
datain = (COMPLEX *) dx->cont;
for (i = 0; i < dx->numelems; ++i)
dataout[cnt][i] = sqrt(datain[i].re * datain[i].re + datain[i].im * datain[i].im);
nextevent(dataout, dx->numelems);
free(dataout);
This code is called in a loop. dataout is a double array to be sent to the secondary vi, datain is the source data.
The problem now is that there is something eating up memory, and I fail to see why.
My second question is this:
I want to insert a Hamming window, or some other form of windowing function. It doesn't work however, and the help tells me it is because a vi opened this way cannot contain any polymorphic vi. Is there a convenient way around this problem?
Lars Melander
Uppsala Database Laboratory, Uppsala University

Regarding your second question:
As you say not possible to use a polymorphic vi in a DLL and in your case it is the windowing VI that is polymorphic. What you can do is to use only one instance of the windowing VI in the short cut menu.
Here is a link to a report about this error in the knowledgeBase:
