out-of-memory

问题 This is in reference to: byte[] and efficiently passing by reference And the SqlDataReader found in this post: Getting binary data using SqlDataReader Inside a loop, I'm calling a database and returning a large object ( varbinary[max] ). Currently, I'm running into OutOfMemory exceptions, so I'm trying to reduce the footprint in the Large Object Heap (LOH). So, I'm creating a byte array for the largest file that I'd download and adding some padding just in case. For instance: byte[]

问题 My code is doing things like this: for(SomeObject so : someObjects) { Blah b = so; NewObject n = dao.GetNO(b.23); } i.e. it is creating a new variable inside the for loop on each iteration. Could this be the cause of the out of memory issue? The error reported by Netbeans: Caused by: java.lang.OutOfMemoryError: Java heap space at java.lang.StringCoding$StringDecoder.decode(StringCoding.java:133) at java.lang.StringCoding.decode(StringCoding.java:173) at java.lang.String.<init>(String.java:443

问题 My web application is running in apache tomcat. The classloader/component org.apache.catalina.loader.WebappClassLoader @ 0x7a199fae8 occupies 1,70,86,32,104 (88.08%) bytes. The memory is accumulated in one instance of java.util.concurrent.ConcurrentHashMap$Segment[] loaded by <system class loader> . I got this problem while analyzing Heapdump. How to analyze it further ? 回答1: You provide very little information so I only can provide very little advice… ;-) First you need to find out who is

问题 I'm getting quite crazy with this issue: I am getting an OutOfMemoryError everytime I open my app. At some point, it loades an image from a server, but it's encoded y a Base64 string. Whay I do is basically: decodedString = Base64.decode(imagen_codificada); Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); But i'm getting the damned OOME, everytime. If tried with this: BitmapFactory.Options options=new BitmapFactory.Options(); options.inSampleSize = 8

问题 I have a list view that I want to display an image for each item, loaded from a URL. If I use an ImageCell as the DataTemplate, it will load once and then if I try to load again I will get an OutOfMemory error. I next tried the code from Introduction to Xamarin Forms page here http://developer.xamarin.com/guides/cross-platform/xamarin-forms/introduction-to-xamarin-forms/ to create a custom ViewCell class MyViewCell : ViewCell { public MyViewCell() { var image = new MyImage { HorizontalOptions

问题 I am getting the infamous java.lang.OutOfMemoryError: bitmap size exceeds VM budget error . I have several XML layouts and a lot of the elements have images (button backgrounds, Linear layout backgrounds, etc.) After going through the questions posted, like Strange out of memory issue while loading an image to a Bitmap object and external allocation too large for this process and OutofMemoryError: bitmap size exceeds VM budget (Android) and Android: Error loading images: OutOfMemoryError:

问题 I'm getting the following trying to run Cobertura as part of my Gradle build. :cobertura Instrumenting classes for Cobertura Exception in thread "Test worker" java.lang.OutOfMemoryError: PermGen space java.lang.OutOfMemoryError: PermGen space I've tried bumping up DEFAULT_JVM_OPTS / -XX:MaxPermSize in my gradle wrapper script, to no effect. Is there a more direct (and effective) way to do this? 回答1: The only thing that worked for me was changing the .bashrc on my Linux box to have export

问题 I'm just trying to change the background image of the app, it has nothing in it yet and i just wanted to change the background of the main activity to an image. It displays correctly in the preview but when I come to run it either on an emulator or on my physical device I get this error. Throwing OutOfMemoryError "Failed to allocate a 604786188 byte allocation with 4194208 free bytes and 230MB until OOM" The image is less than 1.5MB so I have no clue why it would run out of memory or be

问题 I am trying to concatenate a large character vector (2.8 Gb) with the following code: x <- paste(v, collapse = "\n") Error message: Error in paste(v, collapse = "\n") : result would exceed 2^31-1 bytes As I understand it, this is caused by a limit R imposes on individual objects. However, I have also read that R can support long vectors since R 3.0.0, but cannot figure out how. I have tried increasing the environment variable R_MAX_VSIZE=32000000000 (32 GB) without success. I am running

问题 I have a large image 1.28 MB (1,343,488 bytes) that I use in my app, however I wanted to change a few things and created a new image that was instead only 292 KB (299,008 bytes) in size. I created both images in Photoshop 7.0, saved them both as .png and both as interlaced. I have been creating this app around the larger image, and as soon as I switch to the smaller image, I get an OutOfMemory error with my bitmap saying 12108912-byte external allocation too large for this process why does it
