Eclipse becomes unresponsive

I m using Eclipse Indigo. It becomes unresponsive often and finally prompts saying out of memory error and asks me to exit workbench. I increased the Perm Gen space as told in one of the eclipse forums by editing my eclipse.ini file.

Eclipse.ini file contents now is as below,

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx512m
-XX:MaxPermSize=256m
-vm C:/Java/jdk1.5.0_15

I mostly do Javascript development in eclipse. And I am not able to edit JS file in eclipse. What can I do to solve this problem?

Java 5 is pretty old. The GC (and overall optimizations) are slow, outdated and patch level 15 means you're missing many critical bug fixes.

The first step would be to install Java 7 (lastest version). Make sure you disable the browser plugin because of the security risks.

Then make sure that Eclipse uses it: Update the path after -vm. Note: If your path contains spaces, use this:

-vm
c:\Program Files\Java\...

(i.e. put the path into a line of it's own).

Lastly, there are two kinds of memory in Java. Heap and PermGen. The error message tells you which one ran out. Use -Xmx to set heap memory and -XX:MaxPermSize= for PermGen. 256m PermGen should be enough but some script languages need more.

With Java 7, enable GC1 which should give you better performance: -XX:+UseG1GC

This problem may be due to

  1. You are using old java version , You need to upgrade it with new version
  2. If your operation system is 64 bit make sure that you are using 64bit java

Currently maximum only 512MB is allowed for eclipse in your ini (-Xmx512m), if you have enough RAM you shall try increasing it to 1GB. More info here http://wiki.eclipse.org/FAQ_How_do_I_increase_the_heap_size_available_to_Eclipse%3F
