Hi,

I don't know what is happening to my Eclipse installation, but very
quickly uses up all memory.

When Eclipse starts up and opens my workspace it uses about 145 Mb of
memory.
I now this thanks to the Windows Task manager.

Then I begin editing files and so on and when memory reaches about 230 Mb,
Eclipse complains that no more memory available and asks me to quit
Eclipse.

The following is logged in the error log:

java.lang.OutOfMemoryError: PermGen space

My questions are:

* If I start Eclipse with the -Xmx500M flag (eclipse.exe -vmargs
-Xmx500M), why the limit is about 230Mb
* How can I know which plugin is eating my memory?

Thanks in advance for any hint.

You are not running out of Heap you are running out of PermGen Space
(approx 65Mb on Suns vm)
I'm guessing you are using WTP or BIRT or some other very large Plugin.
See https://bugs.eclipse.org/bugs/show_bug.cgi?id=129490 for details on
the problems.
And don't forget to vote on the bug to get it fixed fast.

As a workaround you have to boost your permgensize. Use the
-XX:MaxPermSize=<value> switch to raise Permsize. As mentioned above on
sun JRE1.5 it defaults to 65Mb.

Stefan

Thanks Stefan.

The problem seems to have disappeared since I'm using JRockit JRE 1.5.0_04
instead of Sun's 1.5.0_05.

Nevertheless, I will vote for the bug...
