I am getting this Error with MyEclipse running on Mac OS X, but not on MyEclipse running on Windows XP:

MyEclipse has detected that less than 5% of the 64MB of Perm Gen (Non-heap memory) space remains.

It is strongly recommended that you exit and restart MyEclipse with new virtual machine
memory paramters to increase this memory. Failure to do so can result in data loss.

The recommended Eclipse memory parameters are:
eclipse.exe -vmargs -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M

What does it mean, and what can I do about it? Where can I make these changes to the memory parameters?

Hi Kwame,
By setting these parameters, you are increasing the Perm Space and Heap Space. You’re basically optimizing your memory settings.

This change has to be made in the eclipse.ini file. To get at the eclipse.ini file you need to right click on your Eclipse executable, do “Show Contents” then drill down to the Mac OS folder which should contain your eclipse.ini file inside. On Mac, Eclipse ships quite a few default flags in the eclipse.ini file, so you might want to back it up before changing it.

Thanks for the reply.

These are the contnts of my eclipse.ini file:

-vmargs
-Dosgi.splashLocation=/Users/name/Library/MyEclipse 5.1.1 GA/eclipse/MyEclipseSplash.bmp

-Xdock:icon=../Resources/Eclipse.icns
-XstartOnFirstThread
-Xbootclasspath/p:../../../plugins/org.eclipse.jdt.debug_3.2.1.r322_v20070130/jdi.jar
-Xms128m
-Xmx512m
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Dorg.eclipse.swt.internal.carbon.noFocusRing

But the error message would like me to change to :

-vmargs -Xms128M -Xmx512M -XX:PermSize=64M -XX:PermSize= 128M

So do I append this to the file, or just change the whole file to this?

-vmargs
-Dosgi.splashLocation=/Users/name/Library/MyEclipse 5.1.1 GA/eclipse/MyEclipseSplash.bmp

-Xdock:icon=../Resources/Eclipse.icns
-XstartOnFirstThread
-Xbootclasspath/p:../../../plugins/org.eclipse.jdt.debug_3.2.1.r322_v20070130/jdi.jar
-Xms128m
-Xmx512m
-XX:PermSize=64m
-XX:MaxPermSize=128m
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Dorg.eclipse.swt.internal.carbon.noFocusRing

Add -XX:PermSize=64m and -XX:MaxPermSize= 128m as shown above.

[kwame]

When I insert

-XX:PermSize=64m
-XX:MaxPermSize=128m

into the eclipse.ini file, MyEclipse no longer opens. I get a “JVM terminated” message.

if i take out those 2 lines, it works just fine. Any suggestions

Hi Kwarne,
On some OS, even a simple newline char will screw up the whole thing. Try and put all the memory args on 1 line in the eclipse.ini file and see if it loads it then.

I upgraded to MyEclipse6.0 and again I’m getting the same out of memory error, only now i cant find eclipse.ini to make the adjustments:
-vmargs -Xms128M -Xmx512M -XX:PermSize=64M -XX:MaxPermSize=128M

kwame,
Are there any additional messages being logged under <workspace>/.metadata/.log file ?

[kwame]

Thanks for the reply. Its working now. I think what happened was that I needed to have the arguments on different lines and not all on the same line.

[Loyal Water]

Glad it worked. Thanks for letting me know.
