问题 I've found a strange issue when saving or updating several objects in Grails with MongoDB. Currently I'm using Grails 2.2.3 and MongoDB plugin 1.3.0. The problem seems to be that the instances of MiUsuario are never GC neither when I manually call the GC. In our main application we don't make batch updates, but when doing load tests (with JMeter and monitoring JVM with Java VisualVM) this problem causes memory filling and Tomcat stops responding. I've created a small new application to show

问题 I have found strange issue with method Texture2d.SaveAsPng() Every call 1.5mb disapear. I use this method to save texture to isolated storage public static void SaveTextureToISF(string fileName, Texture2D texture) { using (IsolatedStorageFile file = IsolatedStorageFile.GetUserStoreForApplication()) { using ( IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(fileName, FileMode.Create, file) ) { texture.SaveAsPng(fileStream, texture.Width, texture.Height); fileStream.Close();

问题 There's a memory leak in my script and I couldn't find it after 2 days. I found the loop that is causing the memory leak; each iteration of the loop increases the memory usage. I moved the loop into a function to isolate the variables. At the end of the function, I unsetted every variable created by the function so that get_defined_vars() returns an empty array. Here's what I mean: function the_loop(){ $var="value"; ... // processing, including using a library unset($var); print_r(get_defined

问题 I have ImageView & one button on my ImageActivity. when the button is clicked the available images are listed, when one of them is clicked, it is loaded into the ImageView. imageView xml: <ImageView android:id="@+id/imageView" android:layout_width="300dip" android:layout_height="300dip" android:src="@android:drawable/alert_light_frame" /> Please see the code: public class ImageActivity extends Activity { private static final int SELECT_PICTURE = 1; private String selectedImagePath; private

问题 Debug_VLD in VS2010 reveals some memory leaks that come from class member creation / initialization / deletion. my_member is a data member with type double*. In constructor, I have my_member = NULL ; Then in some method, i need to allocate memory for my_member . I cannot do so in constructor, since i dont know size of array yet, and/or size may different for different calls of the method. What i do in this method is checking if member is NULL. if so, i allocate space for it, if not, i can

问题 I was analysing the following code, which compiles and runs correctly, but generates a memory leak. The cfiboheap is a C implementation of a Fibonacci Heap and the following code is a Cython wrapper (a part of it) for cfiboheap . My doubts starts on the insert function. The object data has been created somewhere and passed to the function insert() . Since the function wants to add this object to the fiboheap it increases its reference count. But afterwards? To whom the ownership goes? In my

问题 I have 2 activities Activity A = GameActivity uses an instance of PhotoTask.class which extends AsyncTask and is used to take and save picture. Once the picture is saved, I start Activity B = ShareActivity. When I take a picture and don't change the orientation, Activity B is called and everything works fine. Yet, if I change the orientation of the screen to take the picture (I pass from portait to landscape) I have errors when I take a picture (Activity B does not start). I even commented my
