I have found that even though java.lang.OutOfMemoryError java.lang.outofmemoryerror android studio is quite common basic knowledge of its cause and solution is largely unknown among junior developers.

deal with this kind of error. You need real experience dealing with production systems, handling a large number of user sessions to troubleshoot and fix performance issues like running out of memory. If you want to be good at troubleshooting and performance analysis, you need to learn some books on Java performance and profiling e.g. Java Performance The

Definitive Guide By Scott Oaks or the Java Performance by Binu John. They are an excellent resource for senior Java developers and also teaches you tools and process to deal with an error like java.lang.OutOfMemoryError. In this article, we will explore what is java.lang.OutOfMemoryError; Why OutOfMemoryError comes in Java application, different type of OutOfMemoryError and How to fix OutOfMemoryError in Java. This article is purely meant to provide basic knowledge of java.lang.OutMemoryError and won't discuss profiling in detail. For profiling read the books I have mentioned before. What is java.lang.OutOfMemoryError in Java OutOfMemoryError in Java is a subclass of java.lang.VirtualMachineError and JVM throws java.lang.OutOfMemoryError when it ran out of memory in the heap. OutOfMemoryError in Java can come anytime in heap mostly while you try to create an object and there is not enough space on the heap to allocate that object. Javadoc of OutOfMemoryError is not very informative about this, though. Types of OutOfMemoryError in Java I have seen mainly two types of OutOfMemoryError in Java: 1) The java.lang.OutOf

Recently, I am running into java.lang.OutOfMemoryError: Java heap space error because I am not being conservative on memory usage. The user can open unlimited number of files, and the program keeps the opened objects in the memory. After a quick research I found Ergonomics in the 5.0 Java Virtual Machine and others saying on Windows machine the JVM defaults max heap size as 64MB. Given this situation, how should I deal with this constraint? http://stackoverflow.com/questions/37335/how-to-deal-with-java-lang-outofmemoryerror-java-heap-space-error-64mb-heap I could increase the max heap size using command line option to java, but that would require figuring out available RAM and writing some launching program or script. Besides, increasing to some finite max does not ultimately get rid of the issue. I could rewrite some of my code to persist objects to file system frequently (using database is the same thing) to free up the memory. It could work, but it's probably a lot work too. If you could point me to details of above ideas or some alternatives like automatic virtual memory, extending heap size dynamically, that will be great. java java-ee jvm out-of-memory heap-memory share|improve this question edited Sep 30 at 14:04 Bhaskara Arani 2791331 asked Sep 1 '08 at 1:10 Eugene Yokota 62.1k35148231 The default max heap size of 64 MB is from before J2SE 5.0. For J2SE 8.0 information, see "Garbage Collector Ergonomics" at docs.oracle.com/javase/8/docs/technotes/guides/vm/… . –Andy Thomas Apr 8 '15 at 15:36 add a comment| 16 Answers 16 active oldest votes up vote 136 down vote accepted Ultimately you always have a finite max of heap to use no matter what platform you are running on. In Windows 32 bit this is around 2gb (not specifically heap but total amount of memory per process). It just happens that Java happens to make the default smaller (presumably so that the programmer can't create progr
like: java.lang.OutOfMemoryError: Java heap space Diagnosis Configure Java to produce a heap dump when it throws an OutOfMemoryError. Heap dumps can be used to determine what was in memory, https://confluence.atlassian.com/confkb/confluence-crashes-due-to-outofmemoryerror-java-heap-space-error-183469749.html and thereby find memory leaks and determine what parts of the system are using too much memory. To generate a heap dump once an out of memory error occurs, add https://www.youtube.com/watch?v=EJw7ArSKBzs the following arguments to your Confluence as per the Configuring System Properties document: -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=
