Question

When i create a new project in "Eclipse" IDE.Suddenly it shows an alert message "Out of memory error".I cannot identify the reason. If any one know the reason please tell me.

Answer 1

Try to start eclipse with follow paramenters:

eclipse.exe -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m

Or justify these parameters for your requirements

Answer 2

1. Go to your Eclipse setup folder

2. If you are running Eclipse on Mac OS X then

   Right click on eclipse.app icon

   Click on Show Package Contents

3. Open eclipse.ini file

4. Change below parameters

   -Xms512m
   -Xmx3000m (Hoping your developer box has >4GB of memory)
   

5. Add below parameters

   -XX:PermSize=256m
   -XX:MaxPermSize=512m
   

Answer 3

The most obvious explanation is that you are truly out of memory. In which case starting Eclipse with a bigger heap should help

 -vmargs -Xmx256M

varying the 256M to see what works for you.

I would not expect to see this problem if you have just a few simple projects. If you are using additional plugins then conceivably the amount of heap you need may need to be increased.
