Eclipse内存不足

Question

I have a ATG Dust Application. To test my ATG application, i linked my ATG App to Dust Application by Right clicking on Dust App -> Build Path -> Link Source -> Select my ATG App. ATG app is a big application. When i try to clean build the DUSt App, i get the exception like "An out of memory exception has occurred. Consult the " Running Eclipse"section....."

In the eclipse .log file has the following exception logged,

// From the Log File   
    !ENTRY org.eclipse.core.jobs 4 2 2014-03-27 06:56:26.549
    !MESSAGE An internal error occurred during: "Launching SampleTest".
    !STACK 0

// Exception
 java.lang.OutOfMemoryError: Java heap space
        at java.util.Arrays.copyOfRange(Unknown Source)
        at java.lang.String.<init>(Unknown Source)

Answer 1

just right-click on your file in eclipse and select as Run as -> Run configuration . It will open Run Configurations Dialog Box .Click on Arguments Tab

Enter this value

                    -Xms1024m -Xmx3072m -XX:MaxPermSize=1024M

In Vm Arguments and press run

Answer 2

The Out of Memory issue is something that occurs due to the improper handling of Heap. You must optimise the code to avoid that. As a temporary fix you can increase the heap space.

-XX:MaxPermSize=512m
-Xms512m
-Xmx1024m

Answer 3

Like Dileep said, the problem is possibly an improper handling of heap space.

Increased heapsize might not solve the problem, but work around it for a while. You can set the parameter -XX:+HeapDumpOnOutOfMemoryError in your eclipse.ini . This will write a heapdump out, which can be analzed by tools like Eclipse Memory Analyzer . Try to make sure that you don't have a memory leak before using up more space.

in your case java.util.Arrays.copyOfRange is copying parts of Arrays around. you could start with checking what size they are.
