Memory leak in glTexImage2D on iPhone ?

I'm working on a program that involves the movement of a texture on top of a 3d object. The texture is moved via the following code on a touchmoved event. The code runs, and the display is exactly as expected(and correct. The problem is, every time this code runs it looks like both the context and the gltexture are creating memory blocks that never get freed. After about 15 seconds of movement this is consuming 1gb of ram.
-- code --
CGImageRef blockRef = CGImageCreateWithImageInRect([img CGImage], CGRectMake(imgWidth - clipx, clipy,texsize,texsize));
CGContextRef spriteContext = CGBitmapContextCreate(spriteData, tex_size, tex_size, 8, tex_size * 4, CGImageGetColorSpace(blockRef), kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
CGContextDrawImage(spriteContext, CGRectMake(0,0,(CGFloat)tex_size, (CGFloat)tex_size), blockRef);
glGenTextures(1, &texref);
glBindTexture(GLTEXTURE2D, texref);
glTexImage2D(GLTEXTURE2D, 0, GL_RGBA, 512, 512, 0, GL_RGBA, GLUNSIGNEDBYTE, spriteData);
glTexParameterx(GLTEXTURE2D, GLTEXTURE_MINFILTER, GL_LINEAR);
glTexParameterx(GLTEXTURE2D, GLTEXTURE_MAGFILTER, GL_LINEAR);
CGImageRelease(blockRef);
CGContextRelease(spriteContext);

Added code in a more readable fashion:
CGImageRef blockRef = CGImageCreateWithImageInRect([img CGImage], CGRectMake(imgWidth - clipx, clipy,texsize,texsize));
CGContextRef spriteContext = CGBitmapContextCreate(spriteData, tex_size, tex_size, 8, tex_size * 4, CGImageGetColorSpace(blockRef), kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
CGContextDrawImage(spriteContext, CGRectMake(0,0,(CGFloat)tex_size, (CGFloat)tex_size), blockRef);
glGenTextures(1, &texref);
glBindTexture(GLTEXTURE2D, texref);
glTexImage2D(GLTEXTURE2D, 0, GL_RGBA, 512, 512, 0, GL_RGBA, GLUNSIGNEDBYTE, spriteData);
glTexParameterx(GLTEXTURE2D, GLTEXTURE_MINFILTER, GL_LINEAR);

Memory leak issue in iPhone app

We developed a little program to display PDF's on the iPhone, but it's crashing after scrolling through xx number of pages with low memory error. The app runs fine in the simulator but crashes on the original iphone. I ran the memory leak debugger tool from xcode and got the following:
http://picasaweb.google.com/momopi/MiscCollection#5384555524546579922
(click on magnify glass tool to zoom in)
Weird part is when I run the same on iphone simulator I only get 2 small memory leak warnings (128 bytes each), but on the iphone I get a lot more warnings and it crashes.
Has anyone seen anything like this?

Perhaps you don't have any meaningful leaks. Your program could simply consume too much memory. It has been many years since keeping a small memory footprint was important. Now that Apple has thrown embedded programming to the masses, everyone has forgotten about that.

[iPhone] Memory leak when UIWebview is loaded with URL

I have created a custom browser in my app using UIWebview . A memory leak is seen on everytime webview is loaded with provided url. A snapshot of the leak is shown below.You may note that no back trace is shown and hence cause of leak is unknown.
Snapshot of leak
Please help me with this issue as early as possible.

You might want to take this discussion to the developers forums. This is a general user to user forum for using the iPhone. This is way outside the scope of general use.

SslIoRead memory leak in NSOutputStream (iPhone SDK)

Hi, I am using NSOutputStream to write email to smtp server. I used TLSv1 as security protocol. I found that everytime I open such a output stream and output as TLSv1, there is about 36k memory leak from a call "sslIoRead". Perfermance tool aslo link it to something like this in the code:
[outputStream setProperty:NSStreamSocketSecurityLevelTLSv1 forKey:NSStreamSocketSecurityLevelKey]
Anyone as the same experience, how can I fix it?
Thank you very much.

How to fix huge iTunes memory leak in 64-bit Windows 7?

iTunes likes to allocate as much as 1.6GB of memory on my dual-quad XEON 8GB 64-Bit Windows computer and then becomes unresponsive.
This can happen several times a day and has been going on for as long as I can remember. No other software that I use does this - only Apple's iTunes. Each version I have installed of iTunes appears to have this same memory leak. Currently I am running version 10.7.0.21.
I love iTunes when it works. But having to constantly kill and relaunch the app throughout the day is bringing me down.
Searching for a fix for this on the internet just surfaces more and more complaints about this problem - but without a solution.
Having written shrinkwrapped software for end users as well as for large corporations and governments for more than 25 years I know a thing or two about software. A leak like this should take no more than a day or two to locate using modern software tools and double that to fix it. So why with each new version of iTunes does this problem persist? iTunes for Windows is the flagship software product Apple makes for non-Mac users - yet they continue to pass up each opportunity they have had over the years with each new release to fix this issue. Why is this?
Either the software engineers are not that good or they have been told NOT to spend time on this issue. I personally believe that the engineers at Apple are very good, and therefore am left thinking that the latter is more likely the case. Maybe this is to coax people to purchase a Mac so that they can finally run iTunes without these egregious memory leaks. I would like to offer another issue to consider.
Just as Amazon sold Kindles and Google sold Nexus tablets at low cost - not counting on margin for profit - but instead they wanted to saturate the marketplace with tools for making future purchases of content almost trivial to do with their devices. Apple also counts on this model with their pricer hardware - but they also have iTunes. Instead of trying to get people to switch to a MAC by continuing to avoid fixing this glaring issue in iTunes for Windows I would like to suggest that by allowing their engineers to address this issue that Apple will help keep Windows users from jumping ship to another music app. The profit to be made by keeping those Windows users happy and wedded to the iTunes store is obvious.
By continuing to keep this leak in iTunes for Windows all it does is lower my esteem for the company and start to make me wonder if the software is just as buggy on Macs.

I have same issue. Ongoing for more than 1 year and currently running iTunes 11.3.
My PC is Dell OptiPlex 990 I7 processor, 8GB ram, W7 64 [always keep things patched up to latest OS updates etc]
I use this iTunes install to stream music videos etc to multiple appleTVs, ipads, iphones etc .. via Home Sharing
Store all my media including music, videos and apps on separate NAS .. so the iTunes running on PC is only doing the traffic cop role and streaming / using files stored on NAS .. creates lots of IO across my network
Previous troubleshooting suggest possible contributing causes include
a) podcast updates .. until recently I had this auto updates on multiple podcast subscriptions, presumably the iTunes would flow this from the PC to save on the NAS across the network .. if the memory leak is in the iTunes network communication layer (?bonjour?) this may be sensitive to IO that would not normally occur if the iTunes file saving was local on the same PC
b) app updates .. have 200+ apps in my library and there is always a batch of updates .. some updates 100s of MB is size .. routinely see 500MB to 1GB of updates in single update run .. all my apps are
c) streaming music / movies .. seems when we ramp up streamlining of music or movies . memory leak grows faster .. ie within hours of clean start
c) large syncs of music or videos to ipads or iphones .. noticed that get big problems when I rebuild an ipad .. I typically have 60+ GB of data in terms of apps / music / videos to load .. have to do rebuild in phases due to periodic lockups

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.

Are you guys going to fix the memory leak in version 6

Hi I was wondering if you guys were going to fix the huge memory leak in Firefox 6. As of now I use windows Vista 32bit Ultimate and Firefox is using 164MB of memory to view www.google.com. I'm sorta confused also on how SLOW the browser is. I never seen F.F act this way since F.F 6. I'm hoping that this will be resolved in version 7 cuz this is not cool so slow in all.

On the "flip-side", I had the smoothest and quickest iTunes upgrade/install ever. This was on my Windows 7 Professional, 64bit system.
That you performed an assumedly 'clean' reinstall of your OS, is not a good sign. Obviously, iTunes doesn't like something within your system.
Here are the next steps that I would take if in your position:
- Are you absolutely positive that you have the 64bit version of iTunes?
- Re-download a new copy of the 64bit version of iTunes 10.5
- Try downloading iTunes from one of the 'mirror sites' - FileHippo is good
- Call your PC's manufacturer and see if they are aware of any conflicts with your specific machine's build with respect to iTunes
- Temporarily use another PC (if available) to get your iPhones up and running
Best of Luck

Memory leak in NSUserDefaults

Hi, I have a iphone photography App. In my app, user may open many images. Each time user opens a new image, I will save the image to NSUserDefault so that next time user starts my app, the last image will be loaded.
Here is my code, (I call this method everytime user opens a new image)
-(void) saveDefaults:(
NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];
if (standardUserDefaults){
NSData* imageData = [NSData dataWithBytes:(void*)someMemoryBuffer length:lengthOffBuffer];
[standardUserDefaults setObject:imageData forKey:@"MyImage"];
I do not call [standardUserDefaults synchronize] each time I put a new image in NSUserDefaults. I call it to commit saving image to NSUserDefault only when my program ends.
It seems that there is a memory leak. I used PerfermanceTool, it does report any memory leak, but I can see that the memory token by my App increases everytime I call "saveDefaults" and perfermanceTool points the increase of memory to the "saveDefauts" function. Is there any memory problem in my code.
Thank you very much.

As I have neither an iPhone Developer account nor an iPhone, I can't help very much. Try this link. I don't know if it will help because I can't sign in. You could save your data in SQLite.
You could follow these instructions. Try looking at the official Apple documentation instead.

NIB Resource Memory Leak

I have a question: I have an application that uses lots of views and I tend to load them with NIBs:
MemoryManagementTestViewController *
newViewController = [[MemoryManagementTestViewController alloc] initWithNibName:@"MemoryManagementTestView" bundle:nil];
[self.navController pushViewController:newViewController animated:YES];
[newViewController release];
After I pop the above view controller off the navigation stack, its viewDidUnload() and dealloc() methods are called (below for a test view controller I created to try to isolate the cause of the problem).
The Object Allocation instrument tool shows that a number of control initWithCoder methods (such as UITextField initWithCoder) are consuming memory.
I realize that I am not using the recommended coding style for outlets (my 10 test labels and 10 test text fields), but I have tried to the recommended property style as well.
I cannot think of anything that I am not freeing, but the combination of the code above and below results in a persistent leak, at least according to the object allocator instrument application (though not with the memory leaks tool). Eventually the application runs out of memory as didReceiveMemoryWarning() is called.
I looked at your sample source code, and it appears that most of your sample applications load their views at startup instead of creating and freeing them as I am attempting to do. Is that necessary? If not, is there some trick to free NIB resources?
- (void)viewDidUnload
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
[label1 release];
[label2 release];
// ... labels 3-10 released too.
label1 = nil;
label2 = nil;
// ... labels 3-10 set to nil.
[text1 release];
[text2 release];
// text fields 3-10 released too.
text1 = nil;
text2 = nil;
// text fields 3-10 set to nil.
return;
- (void)dealloc
self.navigationItem.leftBarButtonItem = nil;
[self setView:nil];
[super dealloc];
return;
}

Can I locate "memory leaks" to keep apps from crashing?

Hello clever people,
Since the iPhone 4s is still on the market, I assume that my 2 year old 4s should be able to work fine. However, I am constantly plagued by apps crashing and, most frustratingly, apps often fail to remain running in the background, even with one or no other apps running.
I had a similar issue with my iPad2, just before it ran out of applecare, and the chap had me run through with sending anaylitcs to him, and his conclusion was that a few apps were causing 'memory leaks' - had me reset the iPad and reinstall everything. So I also did this on the iPhone, which did help, but it has not solved the issue. I have also removed most apps from the device, in a bid to locate the offending app.
Searching on Google for "memory leak" only brings up info for developers, and nothing for someone who is actually using their phone and having issues. My usual scenario is going for a bike ride and running Strava, which then cuts out when I stop to take a picture - with no other apps running.
Does anyone know how to solve the issue - return the phone to its 'as new' state, or locate the problem and remove it?
Cheers,
Tobias

There are differenty types of, "resets" ..
Have you tried the folloiwng ??
Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
No data is lost due to a reset.
Use iTunes to restore your iOS device to factory settings

How to determine memory leaks?

I tried in XCODE, the RUN/ Start with Performance TOol / and tried out the various options. I was running my app and looking to see if it would report increasing memory use but it seemed to be looking at my total system (i was running under the simulator). In general what is the recommended procedure for determining memory leaks, which tool to use, and what tracing can i use?
How does one look at the retain count of an object? are there system routines that have knonw leaks?

You took the right path. Once instruments comes up select the Leaks tool. Turn off automatic leak detection. In your app, start off at some known state, do something, and come back to the known state and check for leaks. For instance start off in a view, do something that brings up another view then come back to the original view and check for leaks. Leaks will show you if you leaked. Since you took a very deterministic path then checked it should be straight forward to go to the code and find / fix the leaks. Leaks shows you where the code where the leak was generated.

Memory leak in JSpinner implementation (maybe others?)

Hi,
I am developing an application using Java and Swing, and have run into some problems with memory leaks. After examining the source code and making an example program (provided below), I can only come to the conclusion that there is a bug in the implementation of JSpinner in Sun Java 1.6.0_03.
If one uses a custom model with the JSpinner, it attaches itself as a listener to the model. However, it never removes the listening connection, even if the model is changed. This causes the JSpinner to be kept in memory as long as the model exists, even if all other references to the component have been removed.
An example program is available at http://eddie.dy.fi/~sampo/ModelTest.java . It is a simple swing program that has the JSpinner and two buttons, the first of which writes to stdout the listeners of the original model and the second changes the spinner model to a newly-created model. A sample output is below:
Running on 1.6.0_03 from Sun Microsystems Inc.
Listeners before connecting to JSpinner:
Model value is 0, 0 listeners connected:
Listeners after connecting to JSpinner:
Model value is 0, 2 listeners connected:
1: interface javax.swing.event.ChangeListener
2: javax.swing.JSpinner$ModelListener@9971ad
Listeners now:
Model value is 8, 2 listeners connected:
1: interface javax.swing.event.ChangeListener
2: javax.swing.JSpinner$ModelListener@9971ad
Changing spinner model.
Listeners now:
Model value is 8, 2 listeners connected:
1: interface javax.swing.event.ChangeListener
2: javax.swing.JSpinner$ModelListener@9971adThis shows that even though the model of the JSpinner has been changed, it still listens to the original model. I haven't looked at other components whether they retain connections to the old models as well.
In my case, I have an adaptor-model which provides a SpinnerModel interface to the actual data. The adaptor is implemented so that it listens to the underlying model only when it itself is being listened to. If the JComponents using the model were to remove the listening connections, it, too, would be automatically garbage-collected. However, since JSpinner does not remove the connections, the adaptor also continues to listen to the underlying model, and neither can be garbage-collected.
All in all, the listener-connections seem to be a very easy place to make memory leaks in Java and especially in Swing. However, as I see it, it would be a simple matter to make everything work automatically with one simple rule: Listen to the models only when necessary.
If a component is hidden (or alternatively has no contact to a parent JFrame or equivalent), it does not need to listen to the model and should remove the connections. When the component is again set visible (or connected to a frame) it can re-add the connections and re-read the current model values just as it does when initializing the component. Similarly, any adaptor-models should listen to the underlying model only when it itself is being listened to.
If the components were implemented in this way, one could simply remove a component from the frame and throw it away, and automatically any listener-connections will be removed and it can be garbage-collected. Similarly any adaptor-models are collected when they are no longer in use.
Changing the API implementation in this way would not require any changes to applications, as the only thing that changes are the listener-connections. Currently used separate connection-removing methods should still work, though they would be unnecessary any more. The API would look exactly the same from the view of an application programmer, only that she would not need to care about remnant listening connections. (As far as I can tell, the current API specification would allow the API to be implemented as described above, but it should of course require it to be implemented in such a way.)
Am I missing something, or is there some valid reason why the API is not implemented like this?
PS. I'm new to these forums, so if there is a better place to post these reports, please tell me. Thanks.

Another cognition: It's the following code, that causes the memory to be accumulated:
obj = m_orb.resolve_initial_references("NameService");
ctx = NamingContextExtHelper.narrow(obj);For the first 4 calls to this code the memory usage of the nameservice is unchanged. From the 5th to the 8th call, it's increased by approx. 10KB per call. And thenceforward (beginning with the 9th call) it's increasing by approx. 10MB.
What's going wrong here?

Memory Leaks   Unresponsive Mouse

2009 8 core Mac Pro w/ 24 GB of RAM, ATI Radeon 4870, and a SeriTek PCIe eSATA card (card only has drives connected when running a manual drive clone). When running Toast 10 or Parallels 9, my RAM will fill up (I use a program called Menu Meters to monitor stuff). This machine worked just fine under OS 10.9 and earlier - no issues like this at all. ClamXAV will also completely fill the RAM up (the meter will be full green, instead of part green, then mostly grey when Toast or Parallels fills it up). I have to use Terminal to purge it so that the machine is usable.
The other thing that happens is that sometimes when the computer wakes up or I am in the middle of doing something, the mouse will still move, but the dock will not pop open and the left button the mouse doesn't respond. The right button will open the right click menu, but will not respond normally at all. I have tried a different Magic Mouse, but the problem is the same.
I thought that it may be a problem with the factory RAM and the Kingston RAM not playing nicely together. So I ran it with just the factory 8 GB and then ran it with the Kingston 16 GB - the problem persists no matter which RAM is installed. All of the RAM also passes the memory tests in Rember and TechTool.
So, I need to find out if someone thinks that maybe the bluetooth module may be going bad causing the mouse issues. I also need to find out what is causing the memory leaks. I followed the steps that someone gave on this site to boot into safe mode, repair permissions, reset PRAM, then reset SMC (or the other way around - I did it like they said to). It did nothing to fix the problem.
I need some guidance here. As I stated early on, the machine worked perfectly with OS 10.9. I have WAY too much software that I use, so doing a completely fresh install is out of the question - I don't have time to reload everything. This problem is annoying and I know that I am not the only one having these issues. Any input will be greatly appreciated. Thanks in advance.

Here is the EtreCheck report:
Problem description:
Memory leaks when using Toast 10 or Parallels 9. Mouse also become unresponsive (it will move, but left button does not work and dock will not pop open - mouse problem happens independent of the RAM being filled up - different mouse was tried with same result).

T61 with memory leak on XP for driver battc.sys

Hi
I have an issue with XP where the battc.sys module that is part of Windows XP and responsible for the kernel side of monitoring the battery status. This module continually leaks memory until I have no more kernel paged resources left and programs start to fail on my laptop.
I raised a support case for this with Microsoft and after some investigation and upgrading to the latest T61 power drivers that were released a few days ago on the Lenovo site, MS support told me it is a fault of the T61 and that I would need to disable Microsoft APCI support to stop this memory leak from occuring and to take the issue up with Lenovo.
I have used the verifier tool to confirm that it is the Windows XP SP3 battc.sys memory module leaking.
I am running the latest T61 drivers and fully patch with MS drivers on SP3.
As MS have told me it is the fault of the T61 I am posting this issue here.
Thanks
Stephen

It is memory available to the kernelwhich itself does not show under a process in task manager as far as I am aware (unles it is taken account as part of the system process).
The best way to measure the available kernel memory space available is by using sysinternals procexp.
You need to download procexp and also install the windows debugging tools from Microsoft. Then in procexp set the "Options > Configure Symbols : Debughlp.dll path" to the new debughlp.dll installed with your debu tools and set the symbols path to srv*c:\Symbols*http://msdl.microsoft.com/download/symbols
Then you can choose in procexp "View > System Information" and see the used and total paged and non-paged kernel memory space.
poolmon helps monitor all the symbols that are taking up this memory and verifier lets you drill down to the exact module and the changes in memory for a module that is occuring.
Here are two really good links on it

In my poolmon i notice that Mmst and battc are taking alot of memory after my computer has been running for some time. Mmst being high is normal but battc should not continually be growing as it is which is why I raised the case to MS but they want verification it is not a Lenovo issue.
