Increasing heap size in eclipse - java

I have a problem increasing heap size in Eclipse Luna. While I run my build, it is failing because of reaching the maximum heap size.
I tried all the following options.
Increasing the heap size in eclipse.ini
Then I tried starting the eclipse from command line using this command.
C:\eclipse>eclipse -clean -vmargs -XX:MaxPewrmSize=4G -Xmx4G
And to just change the heap size while running the application, tried to change the heap size Xmx in varaible arguments and program arguments.
All to no avail. What ever change I make, it is not getting reflected in my heap size in eclipse. Please help.

Problem with Intellij and Heap Size Minimum

I am importing this project
https://github.com/scalaz/scalaz
into the Intellij.
But I get a problem with minimum heap size. I am not sure where the size is beeing set. Any advices to fix this problem please:
/usr/lib/jvm/java-8-openjdk/bin/java -agentlib:jdwp=transport=dt_socket,address=localhost:34077,suspend=n,server=y -Xdebug -server -Xms3784m -Xmx3784m -XX:MaxMetaspaceSize=1g -Xss4m -Xmx1536M -Didea.managed=true -Dfile.encoding=UTF-8 -jar
Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size
Process finished with exit code 1
In preferences of Intellij you can set the maximum heap size for sbt:
This works for me - make sure if you open a new project that you check Use sbt shell for imports and for builds. See my default settings in the screenshot.

java.lang.OutOfMemoryError: Java heap space in eclipse project

I know that this is one of the most frequently asked questions, but I've tried everything (or almost everything) and are still at a dead end.
There is an Eclipse project with some SWTBot test cases that fail with java heap space error when I try to run them. In addition, Eclipse also fails with same error after some time of work.
I tried to do the following:
-Set arguments in run configuration like -Xms768m -Xmx1024m
-Set same arguments in eclipse.ini (and also arguments -XX:PermSize=512m,-XX:MaxPermSize=1024m)
-Set runtime parameters in "Configure java" -Xms512m -Xmx1024m
That was not helpful.
I also tried to look at memory usage and max heap space was about 268 mb!
Is there any idea how to cure it?
Thanks,
Max
The screenshot shows the heap size is 256MB. It seems there is no more memory for java to run.
How's the whole physical memory? -XX:PermSize doesn't need to be so much, 128MB or 256MB is enough. And eclipse doesn't need to be allocated too much memory either. -Xms and -Xmx can be the same.

OutOfMemoryError: insufficient memory in IntelliJ?

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.

error(s)_during_evaluation Eclipse

Eclipse debugger just stopped showing variabile data few days ago it always says error(s)_during_evaluation, i tried increasing the ram in ini , tried to reinstall Eclipse JUNO, and installed Eclipse Helios. Nothing fixed this problem
If it is a memory issue you can try increasing the heap size.It is possible to increase heap size allocated by the Java Virtual Machine (JVM) by using command line options.
-Xms<size> set initial Java heap size
-Xmx<size> set maximum Java heap size
-Xss<size> set java thread stack size
For running from command line you can use
java -Xms64m -Xmx256m HelloWorld
If you are using the tomcat server, you can change the heap size by going to Eclipse/Run/Run Configuration and select Apache Tomcat/your_server_name/Arguments and under VM arguments section use the following:
-XX:MaxPermSize=256m
-Xms256m -Xmx512M

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

I'm using Eclipse to run java program class, while I run it i got this error
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
then i changed the VM from the Properties > Run > VM Options, and I run the program again i got a new error,
Error occurred during initialization of VM
Incompatible initial and maximum heap sizes specified
I'm trying to apply stanford libraries in my program, any idea how to solve this error .
to change the VM for Eclipse you can change the amount of the MV from
Windows> Preferences> Java> Installed JREs
from there select the JRE and click edit, then write in the Default VM Arguments: to -Xmx1024M or any other amount of memory ...
Error occurred during initialization of VM. Incompatible initial and maximum heap sizes specified
This probably means that you supplied both -Xms and -Xmx options, and the -Xms (initial heap size) value is larger than the -Xmx (maximum heap size) value.
netbeans provide to change the -Xms only from Properties > run > VM options
I'm not a NetBeans user. However, a brief search of the Using NetBeans 5.0 manual says this is not correct:
Setting JVM Arguments
You can specify JVM arguments for the project in the Project Properties dialog
box. Open the Project Properties dialog box and click Run in the Categories pane
and then type a space-separated list of JVM arguments in the VM Options field.
In other words, you can set any JVM option that your JVM supports.
here is the string that i changed -Xms512m
(Finally he tells us!!)
Add -Xmx512m as well.
For the record, the common JVM options (such as -Xmx and -Xms) are clearly documented in the manual page for the java command. You should READ it CAREFULLY.
To enlarge the VM heap size use -Xmx option, this could solve the error. But it seems it's your coding problem. Perhaps code is in a dead loop to create new object, or a very large object is created in you code, so I suggest you to check code first.
