In our ASP.NET web app we're experiencing a quite extensive memory leak which I am investigating right now. Using WinDbg I got down to the largest memory eaters in our app which are (ran !dumpheap -stat in the WinDbg console to get these): MethodTable Addr Count Overall size Type ... 000007fee8306e10 212928 25551360 System.Web....

I've got a command line script that is running an array() of files through a loop, and using the file name as an argument to call a method on a helper object. Each run through the script, PHP's memory_get_usage reports a larger and larger number 53294264 57019624 61374624 65699176 70230600 75157152 79900392 84630472 89359264 94300016 1...
Here are two methods that return a dictionary of my custom four-propery objects. They make arrays of strings, floats and BOOLs to put in the Chemical objects, then build a dictionary from the arrays. I'm new enough to the whole memory management game that I'm not always sure when I own something and when to release it. I'm making all ...

Hi, After running our stress testing on our ASP.NET application access to internal web services, our mid-tier server (where we host ASMX .NET 3.5 web services) showed close to 1GB of memory consumption. Upon the review of memory dump from mid-tier server, I have found over 1000 objects of Microsoft.Xml.Serialization.GeneratedAssembly.A...
Hi, I am creating a very big buffer (called buffer2 in the code) using CGDataProviderRef with the following code: -(UIImage *) glToUIImage { NSInteger myDataLength = 768 * 1024 * 4; // allocate array and read pixels into it. GLubyte *buffer = (GLubyte *) malloc(myDataLength); glReadPixels(0, 0, 768, 1024, GL_RGBA, GL_UNSIGNED_BYTE, buf...
I have been working on a perl project at work, and came across a strange memory leak. I have boiled down the source of my problem into a contrived example: #!/usr/bin/perl use strict; use warnings; # takes: an array reference # returns: 1 sub g { my ($a) = @_; return 1; } # takes: nothing # returns: the result of applying g ...
Hello, I'm writing an application (basically its yet another iBooks clone) which consumes a lot of memory. Depending on the input data, it's memory footprint can go up to 70-80 MB (as MemoryMonitor states) or even more. It works fine for quite some time, but it tends to increase its memory footprint over time. So lets say you open a boo...

Hello. I'm diving into iOS development and am getting familiar with the tools. At the end of every day, I perform a "Run with instruments tool -> Leaks" on my app to check for any memory leaks I may have implemented that day. It rarely seems to detect any leaks and, while I'd like to think I'm just a natural iOS programmer, I refuse t...
Hi all! I'm fighting a memory leak in a Python project and spent much time on it already. I have deduced the problem to a small example. Now seems like I know the solution, but I can't understand why. import random def main(): d = {} used_keys = [] n = 0 while True: # choose a key unique enough among used previ...
I'm new to HTML5 application. And I'm making in-house software. This means I can force users to use only most recent version of firefox/webkit. I saw many documents concerning about JS memory leaks in these point: Circular references. Event handlers. Closures. As I think, it's just a problem of only (old version of) IE. But I cannot...
Hi Forum I have a mutableArray that I fill up with objects. When I try to refill the array, I first use removeAllObjects - which produces a memory leak... The properties of the object are synthesized, retained and released on dealloc. The Array is initialized on viewDidLoad like this: theArray = [[NSMutableArray alloc] initWithCapaci...
Hi guys, I'm new to iphone and objective-c development and want to ask if Clang Static Analyzer is enough for getting rid of memory leaks? I personally found the xcode "Leaks" tool rather difficult to use, besides I've seen some articles, where it reads that it will always show memory leaks, even if there are no any real leaks. If I don...
