Hi I am having a memory leak problem and it is actually generating from the following structure array: TagStruct TagData [] = { { Tag_SecurityToken, string("x-abc-security-token"), string("ab-security-token") } , { Tag_XYZ, string("x-abc-xyz"), string("ab-xyz") }, { Tag_ChunkCount, string("x-abc-meta-chunk"), string("ab-me...
I have an ASP.NET MVC app that creates a Linq2SQL datacontext on a per-web-request basis using Castler Windsor IoC. For some reason that I do not fully understand, every time a new datacontext is created (on every web request) about 8k of memory is taken up and not released - which inevitably causes an OutOfMemory exception. If I forc...

Hi, I have a memory leak issue in my application which loads a large amount of images. I'm rather new to C#, and thought my days of memory leak issues were past. I can't figure out the problem - maybe I'm using some unmanaged modules which I'm not handle correctly? To illustrate my problem I've simplified the core of what causes the p...
I am now trying to detect memory leak in our java codes. I understand there are a few of detection tools such as memory manager that comes with eclipse, and NetBeans. Based on your experience, which is the best free tool out there I can use? I tried memory manager, but it is not very easy to detect where the leak is. I heard that NetBean...
With RAM typically in the Gigabytes on all PC's now, should I be spending time hunting down all the small (non-growing) memory leaks that may be in my program? I'm talking about those holes that may be less than 64 bytes, or even a bunch that are just 4 bytes. Some of these are very difficult to identify because they are not in my own ...
I am trying to clean up my code from memory leaks and I am having problems with the 'release' method. Here is my code: NSArray *dict = [[NSArray alloc] initWithContentsOfURL:url]; if (dict == nil) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Cannot retrieve content. Please try again la...
I've got a desktop program. Most Operating Systems run the program in its own address space. When the program exits, I believe most operating systems free the memory allocated by the program and return it to the memory stack for reuse. What I am not sure of, is if the program has a memory leak, will the memory "leaked" also be returne...
Hi all, I have a little problem with memory management in a Windows Service written in C# (framework 3.5, visual studio 2008).

Have you an idea to how resolve t...
Hi, I'm having trouble deallocating a UISCrollView that contains images. There's something wrong with my code, but I cannot understand where. this is a snippet of my code. It basically create a loops adding a uiscrollview with an image and removing. If you run the code with instruments, no memory will be freed. I also add some check for...
There is a memory leak in my application. The memory consumption shoots up after a couple of days of running the application. I need to dump call stack information of each orphaned block address. How is it possible with WinDbg? I tried referring to document created by my colleague, but I'm confused about how to specify the symbol path ...

Hello, I'm at my first experiences with iPhone development. I wrote some basic code to test the NSScanner class, and now I was looking into the Leaks tool. It seems that this code is leaking, when in the detailed stack I double-click my last call (before Apple's stuff), the incriminated line is the commented. Can anyone help me to under...
I have a method that analyzes pixel data inside an NSBitmapImageRep that is built from a CGImageRef. Here is the relevant code: CGImageRef ref; // omitted code for initializing ref NSBitmapImageRep *bitmapRep = [[NSBitmapImageRep alloc] initWithCGImage:ref]; uint32* bitmapPixels = (uint32*) [bitmapRep bitmapData]; // do stuff with bitma...
Say you have the following ANSI C code that initializes a multi-dimensional array : int main() { int i, m = 5, n = 20; int **a = malloc(m * sizeof(int *)); //Initialize the arrays for (i = 0; i < m; i++) { a[i]=malloc(n * sizeof(int)); } //...do something with arrays //How do I fre...
I'm debugging this database project. It wraps access to SQLite for a higher level application. It's designed to run asynchronously, that is, it has methods like ExecuteRequestAsync() and IsRequestReady(). When ExecuteRequestAsync is called, it spawns a boost::thread to do the job and return the function immediately. When the higher level...
What are the most frequently encountered causes for COM memory leaks? I have read that passing the address of an initialized CComBSTR to a function as an [out] parameter causes leak. I'm looking to enumerate other common programming mistakes like this. ...
