out-of-memory

问题 In a project of mine I constantly compress little blocks of data. Now I find out that the jvm then grows to 6GB of ram (resident (RES) RAM, not shared or virtual or so) and then die because of out of memory. It is as if the garbage collector never runs or so. I've pulled out the relevant code and pasted it below. When I run it (java6, 32 bit linux) it grows to 1GB of ram. Anyone got an idea how to reduce the memory usage? import java.util.Random; import java.util.zip.Deflater; import java

问题 As we all know, there are multiple reasons of OutOfMEmoryError (see first answer). Why there is only one exception covering all these cases instead of multiple fine-grained ones inheriting from OutOfMEmoryError ? 回答1: I'd expect because you really can't do anything else when that happens: it almost doesn't matter WHY you ran out, since you're screwed regardless. Perhaps the additional info would be nice, but... I know tomcat tries to do this "Out Of Memory Parachute" thing, where they hold

问题 In one of my VB.Net applications i am getting error while running the application. This error does not come always. So i am not able to reproduce the error also. No exact sequence also to reproduce the error. Stack :System.OutOfMemoryException: Out of memory. at System.Drawing.Graphics.FromHdcInternal(IntPtr hdc) at System.Windows.Forms.ToolStrip.OnPaint(PaintEventArgs e) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System

问题 I have a program that sometimes throw OOME, I understand that there is a flag in the JVM options that I can set and whenever a certain Error/Exception appears (such as OOME) it calls a script I wrote. The script will give the user a notification and will call a the program with a different argument so it won't get OOME again. does anyone know how to set this flag? what is the JVM options I need to set? I looked everywhere on line and couldn't find the answer. help me please! Thanks, Aye 回答1:

问题 Given the opportunity to rewrite, I would, but anyway, the code as it stands: List<string> foobar; Then we add a bunch of strings to foobar. At count=16777216, we hit an out of memory limit. My understanding is that each string would be a different size. Indeed looking at the data (not my data), most are 2 or 3 characters. what is the max limit of data into list in c#? indicates that the max limit is: The maximum number of elements that can be stored in the current implementation of List is,

问题 We are using JBoss_4_0_4_GA with JDK 1.5.0 (no updates) on a Windows The JBoss server is run within a Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.org. Since the JVM is so old I cannot even use the -XX:+HeapDumpOnOutOfMemoryError option on the JVM. What are my option to find out the issue? As usual the Out of Memory exception is happening on different parts of the application. I do not have the liberty to upgrade the JVM right away. The current VM settings Java Additional Parameters

问题 In our JavaEE6 project (EJB3, JSF2) on JBoss 7.1.1, it seems we have a memory leak with @ViewScoped beans. Last tree days I've spent time on this issue investigation. So i've created simple project with two pages to guarantee that after first page leaving @ViewScoped bean will be released. <context-param> //web.xml <param-name>javax.faces.STATE_SAVING_METHOD</param-name> <param-value>server</param-value> </context-param> <context-param> <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name

问题 So here's the deal, I've searched every single question and link online but none are helpful. I have 120 frames of an animation in .jpg format for my splash screen. I understand that jpegs are converted to bitmaps on memory so that's why I get an OutOfMemoryError. The maximum frames I get to animate are 10. Is there any way to do this frame by frame, or should I try something else. Here's my code: final AnimationDrawable anim = new AnimationDrawable(); anim.setOneShot(true); for (int i = 1; i

问题 I’m trying to parse a XML file up to 500 mb in java. I tried to use SAX but it gives me this error java.lang.OutOfMemoryError: Java heap space at com.sun.org.apache.xerces.internal.util.XMLStringBuffer.append(Unknown Source) Can you help me? Thanks a lot. P.S. Smaller XML files works just fine 回答1: Most likely you're not using SAX correctly, or your application isn't suited for stream processing. The whole point of SAX is to avoid keeping the entire XML structure in memory, but that's only
