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 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.
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 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...

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

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.

Memory Leak in TCL UDP socket

Hi all,
I am currently looking at a memory leak issue in the TCL UDP socket configuration when the fconfigure command is issued under a procedure.
Under a normal scenario where the socket is configured globally, the system handles the memory well and we do not see an increase.
The folowing examples are not the actual code implemented but provide an example of the condition under which the leak is seen.
set msg [udp_open]
fconfigure $msg -blocking false -buffering none -translation binary -remote [list 10.70.0.112 1234]
proc send {} {
   global msg
   puts -nonewline $msg "HELLOHELLOHELLOHELLOHELLOHELLOHELLOHELLOHELLO"
   return
set done 0
while {($done <= 1000)} {
   set done [expr {$done + 1}]
   after 250
    send
If we wish do dynamically modify the parameters of the socket, we get an ever increasing consumption of memory (show memory dead - decrease in processor free). for example:
set clients [list]
lappend clients "10.70.0.111 1234"
lappend clients "10.70.0.112 1234"
set msg [udp_open]
fconfigure $msg -blocking false -buffering none -translation binary
proc send {} {
   global clients
   global msg
   foreach peer $clients {
       fconfigure $msg -remote $peer
       puts -nonewline $msg "HELLOHELLOHELLOHELLOHELLOHELLOHELLOHELLOHELLO"
   return
set done 0
while {($done <= 1000)} {
   set done [expr {$done + 1}]
   after 250
    send
I have tested multiple scenatios using flush, return, closing and opening the socket within the procedure, all to the same result - fconfigure in a procedure creates a memory leak in line with the data rate passing through the socket.
I am seeing this across multiple device types and IOS (819,5915,5940,2901,2921,3945) 15 series M/T/GC IOS. I guess the question is, is there a problem with the construct of the procedure in which I am missing something on the channel side to release the memory or does this appear to be a bug?
any help would be appreciated.
Regards,
Robert.

Hi,

Premiere Elements 9 memory leak

Operating system Window 7 64-bit. Using Premiere Elements 9 after loading a project task manager shows memory continuously increasing and eventually Elements slows to a crawl. Has anyone else seen this problem and is there a fix for it? One site said to disable elements autoanalyzer, but couldn't find it in any of the menus. HELP

I can confirm that autoanalyzer did at one time have a memory leak with PrE 9. Autoanalyzer options configured in the Organizer. Hit the menu and submenus Edit / Preferences / Media-Analysis. Make sure to uncheck both Analyze Photos for People Automatically and Analyze Media for Smart Tags Automatically. Click on OK. Shut down PrE and Organizer and reboot just to make sure the process cleanly goes away.
The memory leak was fixed with PrE 10.

Firefox 6.0 has memory leak

Firefox 6.0 (release) has a memory leak.
Tested with 5 windows and 43 pages loaded and left overnight, it crashed after several hours. Able to fully repro this every time.
I left it for 10 mins after all pages loaded. I opened Task Manager and I can see the Memory (Private Working Set) increasing every few seconds.

Well I'm using 7 beta and my memory usage is just short of 600,000k with plugin container using another 220,000k. There is a massive problem with this!

3.6.7 Lag, Delay, Memory Leak Checked But Not Fixed?

Well, open a tab, try to open another tab, about 20 seconds of appearing frozen passed.
Okay let's try clicking the first tab again, oh well, another 20 seconds frozen with cursor not even usable.
Okay let's try clicking the url bar, oops, another 20 seconds of delay, and the program is up to 180 megs of memory, that spikes down to 150, then builds again, apparently a new routine is added to "clear" the memory every so often, however, THE MEMORY LEAK ITSELF REMAINS UNTOUCHED.
Maybe Firefox has become so disgustingly bloated with worthless and useless "innovations" that stroke the egos of its developers that, finally, the program is worthless for daily use.
Second Life is a program that's been around for a very long time, and just open firefox, then Second Life. First, you log in to second life wearing the image of the webpage you have open in Firefox. Then you notice that Second Life is lagging endlessly, sometimes with 5 second delays trying to select anything. Close Firefox, and Second Life performs properly. Amazing isn't it?
Memory issue is THE MOST IMPORTANT FIRFOX ISSUE but apparently no one cares, too busy appreciating themselves for some part of the program that was their idea I guess.
Who cares if 3.5 Firefox is the first to have video without a plug in, if, the program is memory leaking like the BP well was leaking oil??
But, as one can see with a memory monitoring program, Firefox now, finally after almost 20 revisions, has a "fix," to lower the amount of memory along some time-line that seems to keep it from accumulating to 500 megs in a matter of minutes, but, WITHOUT ACTUALLY FIXING THE CAUSE OF THE MEMORY LEAK.
I wonder if these volunteers for Firefox are unemployed, and that's why they have time to work on Firefox, their lack of competence the reason they are unemployed, long before this recession.
FIX THE MEMORY LEAK THAT STARTED WITH 3.5 ALREADY! PUT EVERYONE ON THAT INSTEAD OF ANYTHING ELSE!
P.S. My extensions have nothing to do with Firefox's lack luster performance. The issues have existed with or without them installed. Reality: Firefox programmers are busy with head inserted in hindquarters, feeling good about themselves for volunteering, irrespective of coding pure junk. Quality and doing what is right have apparently been thrown out the door, and the message, "a free internet means you get worthless products" the message of Mozilla.org.
== This happened ==
Every time Firefox opened
== version 3.5

same basic idea- ctrl-shift-del (clear everything) and it went from taking >700megs on startup (PC XP,all addins disabled) to ~60megs.
Better wtf is what was stored in that 650+ megs?

Makequeues memory leak when using Lexmark Z53

Behavior with printer switched off while connected to built-in USB port:
Problem 1: makequeues has a memory leak, starting up with between 3 and 5 MB of RAM. This is done by connecting the printer when logged in and watching via Activity Monitor.
Initially makequeues has sent 255 Mach messages. Every ~10.5 seconds, makequeues sends 59 more messages and gets 53 in reply. With each send/receive cycle, its RAM usage grows by 8 KB, a rate of 780 kiB/min.
Problem 2: The process is started each time the same printer is reconnected.
Symptoms: Disconnecting the printer doesn't let the process exit (any instance). If left alone, the memory usage cycle continues.
The memory leak caught my attention after taking up over a half-gigabyte of RAM when I left the Mac running over night.
Resolution:
(1) Disconnect USB cable
(2) Kill each instance of the process
Results:
(1) The process launches after reconnection of the printer with 996 KB of RAM, immediately having sent 60 Mach messages and received 56.
(2) During this run time, the process may use less and less RAM, down to a minimum of 912.
(3) After sending 64 more messages without replies, one every 4 seconds, the process exits after having sent a total of 120 messages.
(4) This behavior (1 through 3) is the same for each process launched as a result of printer reconnection.
This behavior isn't shown during Safe Mode boot - makequeues never starts up as a result of printer connection.
PowerMac G4 QuickSilver 2001 733Mhz

If this is meant to be a bug report, please file a bug report in the proper place. This is a user to user discussion forum.
As to the source of running 'makequeues' (/System/Library/SystemConfiguration/PrinterNotifications.bundle/Contents/MacOS /makequeues), I would look at the Lexmark software. I currently have two Epson printers connected via USB with CUPS running. I see no process 'makequeues' appearing.

FCE "out of memory" - QT7 memory leak ?

when I try to render a large number of audio clips in FCE, after rendering about 15 mins of clips, it stops with "out of memory" error.
when I look at Activity Monitor while this is happening, I see the VM figure for the FCE process grow and grow until it hits 3.50GB then the error is thrown.
It looks like a memory leak ... with each clip some VM is allocated but not released and eventually the allocation hits an OSX/hardware limit.
the behaviour seems to have started since upgrading from QT6 to QT7.
have others observed this ?
my current workaround is to select 12mins of audio, render the selection, exit FCE to release the VM, open the project again and repeat. very time consuming.

I also have this problem, and stumbled onto the same workaround as others: render ~15 minutes of audio, quit, restart. A real nuisance!
I also have seen the rendering of audio "complete", but in fact the audio disappears after some point in the (long) clip. I haven't found any way to re-render it, so I've been forced to reimport the whole clip and start over. Arrrgh! Any of you seen this problem?
From the symptoms, the root cause does seem to be a memory leak in the audio code (QT?) There's a QT forum posting that seems to indicate the same.
Any comments/prognosis from anyone at Apple?
