Tomcat Java.lang.outofmemoryerror: Java Heap Space
to increase the maximum heap size via Tools -> Servers -> on the Platform tab there is a VM option below Java Platform. Then it works fine.. Now my issue is i'm building the WAR file, directly deployed and run in my another machine Tomcat for demo, here i'm facing the same issue java out of memory error-heap space i also tried with environment variable set CATALINA_OPTS=-Xms512m -Xmx512m this also didn't help me how to resolve this issue?, Please point me java.lang.outofmemoryerror thrown from the uncaughtexceptionhandler in thread "main" to the right direction java tomcat out-of-memory share|improve this question asked Sep 11 '12 at 9:47 Sathish 1,67131642 1 Make it -Xmx1024m and try again. –duffymo Sep 11 '12 at 9:49 where in the environment variable? –Sathish Sep 11 '12 at 9:50 Edit the start script. –duffymo Sep 11 '12 at 9:53 Finally i found the solution for the issue see my answer below –Sathish Sep 11 '12 at 11:15 add a comment| 3 Answers 3 active oldest votes up vote 9 down vote Try to set PermSizeand MaxPermSize values. and that should be set at tomcat startup in Catalina.bat and then stop and start using this script. set CATALINA_OPTS=-server -Xmx1024m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m http://javahowto.blogspot.co.uk/2006/06/6-common-errors-in-setting-java-heap.html share|improve this answer edited Sep 11 '12 at 10:09 answered Sep 11 '12 at 9:51 amicngh 5,80521435 where i have to set this? –Sathish Sep 11 '12 at 9:52 updated the answer , plz check. –amicngh Sep 11 '12 at 9:53 @Sathish which env are you using ?

Tomcat Crash
time, Tomcat may hits the following java.lang.OutOfMemoryError: PermGen space error. java.lang.OutOfMemoryError: tcat tomcat PermGen space at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) It's usually happened after the Tomcat restarts how to take heap dump in tomcat a few times.1. SolutionBy default, Tomcat is assigned a very little PermGen memory for the running process. To fix it, increase the PermGen memory settings by using http://stackoverflow.com/questions/12366989/java-out-of-memory-error-heap-space the following Java VM options. -XX:PermSize
in Atlassian Cloud apps, the contents of this article cannot be applied to Atlassian Cloud applications. Purpose Java applications like JIRA, Crowd and Confluence run in a "Java virtual machine" (JVM), instead of https://confluence.atlassian.com/confkb/how-to-fix-out-of-memory-errors-by-increasing-available-memory-154071.html directly within an operating system. When started, the Java virtual machine is allocated a certain amount of memory, which it makes available to applications like Confluence. By default, Java virtual machines are allocated 64Mb http://gis.stackexchange.com/questions/10428/geoserver-java-out-of-heap-space-how-do-i-increase-it of memory, no matter how many gigabytes of memory your server may actually have available. 64Mb is inadequate for most Confluence installations, and so this needs to be increased. Diagnosis Expand to see out of diagnosis section Determine type of error message Look in the atlassian-confluence.log to see which type of OutOfMemory Error you're receiving. There are three common messages: Heap Space Perm Gen Space GC Overhead This document discusses increasing memory to address PermGen and Heap space errors. Follow the links above to assess root causes for each issue. For GC Overhead, refer to Confluence Crashes Due to 'java.lang.OutOfMemoryError GC overhead limit exceeded'. out of memory Determine Confluence's usage patterns In Confluence, go to Confluence Administration > System Information , and look at the memory graph during times of peak usage: This server has been allocated a maximum of 650Mb and a minimum of 256m. You can see the minimum displayed here; if you're trying to see whether your settings are being picked up, this is where to look. Determine available system memory On Windows From the Close Programs Dialogue (Press ctrl-alt-delete), select the Performance tab: The amount marked Available is the amount in kilobytes you have free to allocate to Confluence. On this server we should allocate at most 214Mb. On Linux Run cat /proc/meminfo to view the memory usage. Setting the -Xmx above the available amount on the server runs the risk of OutOfMemoryErrors due to lack of physical memory. If that occurs the system will use swap space, which greatly decreases performance. Guidance The default values supplied with Confluence stand-alone are sufficient for most installations. Please refer to Managing Application Server Memory Settings and Server Hardware Requirements Guide for a discussion. Solution Step 1: Increase Available Memory We aren't really able to give a concrete recommendation for the amount of memory to allocate, because that wi

I got as far as configuring it with some fairly large shapefiles from a project I've worked on previously. My question is related to a problem which I see if I show the shapefile using the OpenLayers layer preview option. I see an error: OpenLayers map preview code="internalError" Rendering process failed. java.lang.OutOfMemoryError: Java heap space Googling has led me to plenty of Java command line options to increase heap space, but I have no idea if this should be applied to an environment variable, in a startup script or as a part of the Geoserver config. Can you help me to understand what I need to edit to get this working? I'm also wondering if I should be splitting my shapefile into smaller pieces and so any guidelines on this matter would be helpful too. Thanks! geoserver java performance share|improve this question edited Feb 11 at 15:49 artwork21 23.6k44399 asked May 31 '11 at 9:42 Elliveny 13314 add a comment| 3 Answers 3 active oldest votes up vote 1 down vote accepted You must change memory heap in your JVM. I supposed that gisvm.com use Tomcat, so you can find a lot of tutorials about "increase java heap space in Tomcat" in google. Basically is add -Xmx128m parameter to JVM to increasing memory heap. share|improve this answer answered May 31 '11 at 12:35 angelcervera 267312 1 Ah, ok, I found that /etc/default/tomcat6 contains this line: JAVA_OPTS="-Djava.awt.headless=true -Xmx128m -XX:+UseConcMarkSweepGC" - I guess I edit that? Trying -Xmx512m ... –Elliveny May 31 '11 at 15:22 I tried it and it worked! Thanks for the pointer to Tomcat, I hadn't realised that it was involved. –Elliveny Jun 1 '11 at 9:57 add a comment| up vote 4
