When I'm using the graphical layout editor after 5-10 minutes of working I get the error "java heap size". I tried to increase size in eclipse.ini:
-Xms512m
-Xmx1024m
But it doesn't helped. Please tell me who encountered this problem and how to solve it?
Your eclipse.ini settings will take effect only if you change following:
Run -> External Tools -> External Tool
Configurations. go to configuration that u use, under jre tab -select option
Run in same JRE in workspace.
For more info on the topic have a look at this link. What are the best JVM settings for Eclipse?
If sometimes you get this error and smetimes doesn't then It might happens because RAM is being used by other processes which require large memory. Close all the other Applications/processes and try to start/load the eclipse. It works.
You can set this on the command line before running eclipse so that eclipse has more mem: How do I set Java's min and max heap size through environment variables?

I am facing a problem with Intellij 2019.2.1 version to which I recently upgraded. I have set up the Xms and Xmx in the Intellij Help -> Edit Custom vm options and I have also manually set up the same properties in idea64.exe.vmoption and idea.exe.vmoption as well. like below :-
-Xms128m
-Xmx10g
Now, when I am starting my application, in the VM argument of the application I am passing -Xmx800m then on runing the application it throwing an error stating that "Initial heap size set to a larger value than the max heap size".
Could some one please suggest what wrong configuration I am putting here or am I missing something.
IntelliJ IDEA VM options (Help | Edit Custom VM Options) have no effect on the VM options of the apps you start from IntelliJ IDEA. These are only for the IDE runtime JVM, not for your own apps that you develop.
Post a screenshot of the run/debug configuration showing the VM options field. What type of the configuration is that? It's possible that you have defined global system environment variables that set the initial heap size to some large value (-Xms). Make sure you don't have _JAVA_OPTIONS and JAVA_TOOL_OPTIONS environment variables set. If you do, remove them and logout/login or reboot for the changes to apply.
If the project is imported from Maven and you are running tests, pom.xml may supply the VM options, search pom.xml for for -Xms and either remove this option or make it lower than -Xmx.
If the project is Gradle based and you run it via Gradle, the options you have defined in gradle.properties via org.gradle.jvmargs will have effect. Make sure you don't override -Xms there. You can also switch to IntelliJ IDEA run option to not use Gradle options.
I have spring app, with intelliJ (community edition), ant, tomcat 8.5. There is build.xml (ant) file that works for others, but in my case it gives me an error :java.lang.OutOfMemoryError: Java heap space.
I have already tried:
Creating setenv.bat (I'm on windows) set JAVA_OPTS=-server -Xmx1024m.
Then, setting CATALINA_OPTS/JAVA_OPTS/ANT_OPTS system env. variable to -Xms512m -Xmx1024m
Then in Configure tomcat(GUI) -> Java -> Initial memory pool and Maximum memory pool to 512 and 1024.
Then in idea.exe.vmoptions (intelliJ), changed -Xms to 512m and -Xmx to 1024m
But it keeps giving me an error about not enough heap space, while other app (spring mvc as well) works perfectly fine on the same computer with the same intelliJ and the same tomcat configuration (but with maven).
I will download JVisualVM to get better overview what is happening but in the meantime maybe someone could give me a tip what else I could try to fix it?
When I run my project in IntelliJ in debug mode I get the following error.
Does anybody know what is the cause?
I already increased my heap size in idea.vmoptions:
-ea
-server
-Xms1g
-Xmx3G
-Xss16m
-Xverify:none
-XX:PermSize=512m
-XX:MaxPermSize=1024m
I already increased my heap size for compiler to 1024 as bellow:
Try Run menu -> Edit Configurations... -> find your project in the tree of projects on the left, look for VM options: in the panel on the right, and enter something there, according to information found here: What are the -Xms and -Xmx parameters when starting JVM?
That having been said, I should also add that if you are running out of memory without knowingly doing extremely memory hungry stuff, then what you have in your hands is a bug which is causing your program to do runaway memory allocation, which will always be resulting in out-of-memory errors no matter how much you increase your heap size. In that case, you will need to look at your code, not at your project options.
It is very strange still i don't understand why but I resolved it by decreasing the size of VM Options: -Xmx820m.
Maybe because i use jre 32 bit en my Intellij IDE runs on 64 bit.

I have updated the jdev.conf file to include the following, but still receive the error:
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx512M
AddVMOption -Xms512M
Furthermore, this project opens just fine without issue on a colleague's computer, where the jdev.conf file -XX:MaxPermSize=512M switch is set to 256M and the other 2 switches are not present.
I've spent the afternoon playing with different settings, trying to discover the difference, and I am left stumped. Is there something I'm missing? When I try to bump the setting to higher memory limits, JDeveloper fails to start the Java machine (I suspect that is related to memory allocated to Java itself), though it shouldn't be necessary, as the app works fine on my coworker's computer with half the memory allocated to JDeveloper.
I faced the same issue and it get resolved with the help of below link :
Fixing java.lang.OutOfMemory Java Heap Space error in JDeveloper
Beside changing the configration fieles (jdev.conf and ide.conf) to have the commands
JDEV.CONF
AddVMOption -XX:MaxPermSize=256M
IDE.CONF
AddVMOption -Xmx768M
AddVMOption -Xms256M
See also this link:
Jdeveloper throwing Out of Heap Space error with SVN
Beside, stop versioning option for Jdeverlper as follow:
In JDeveloper -> Choose Versioning menu -> Choose Configure -> Uncheck “Versioning support for Subversion”
You can use some standalone SVN clients such as TortoiseSVN for
versioning
Egh. Simple, REALLY obvious solution that we just somehow overlooked. He is running an older version of JDeveloper. Installed that version, everything works.
I'm developing web application in jsp/servlet,i had an issue with netbeans and Java. My program needs large data process. So I used -Xmx512m 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 to the right direction
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 -Xms1024m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m
http://javahowto.blogspot.co.uk/2006/06/6-common-errors-in-setting-java-heap.html
Finally i found the solution for the issue
in Catalina.bat file
you can find some text like below
set _EXECJAVA=%_RUNJAVA%
set MAINCLASS=org.apache.catalina.startup.Bootstrap
set ACTION=start
set SECURITY_POLICY_FILE=
set DEBUG_OPTS=
set JPDA=
under that you need to put the
set CATALINA_OPTS=-Xms512m -Xmx512m
Heap size is larger than your computer's physical memory. For example,
java -Xmx2g BigApp
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
The fix is to make it lower than the physical memory: java -Xmx1g BigApp
I know I am totally late on this reply but in case it would be helpful to anybody runs into the same situation I think it worth to put a note here. I am referring to tomcat 9 so you might need to check how things mentioned here are relevant to your version:
In %CATALINA_HOME%/bin/catalina.bat, it clearly stated that:
rem WHEN RUNNING TOMCAT AS A WINDOWS SERVICE:
rem Note that the environment variables that affect the behavior of this
rem script will have no effect at all on Windows Services. As such, any
rem local customizations made in a CATALINA_BASE/bin/setenv.bat script
rem will also have no effect on Tomcat when launched as a Windows Service.
rem The configuration that controls Windows Services is stored in the Windows
rem Registry, and is most conveniently maintained using the "tomcatXw.exe"
rem maintenance utility, where "X" is the major version of Tomcat you are
rem running.
If you check your %CATALINA_HOME%/bin folder, you could find a file named like "tomcat9w.exe". Double click on it and you could see this screen shot where you can set your Xms and Xmx parameters for it to save into registry for you
Hope this helps
Out of memory error can be result of big session-timeout number in Tomcat's web.xml. In that case many web sessions can take many system memory.
I suggest you enable heap dump and analyze using IBM support Workbench (which has heap dump analyzers) and understand the problem exactly and make configurations accordingly.
