OutOfMemoryError: PermGen space when running eclipse 3.3 on ubuntu

hi,

I keep getting this error when I run eclipse 3.3 on ubuntu. Can anyone help?

probably you'll need to increase the Java heap space here is how

Thats Right, it looks like your PermSize is running out of room.

I haven't done this on my ubuntu setup as yet, but I think this might be how to fix it
Go to where you set up your JAVA_HOME for example:

gedit ~/.bashrc

add

export JAVA_OPTS=-Xms128m -Xmx128m -XX:MaxPermSize=128m

Increasing the MaxPermSize should fix this error.

Let us know if that helped...

If you navigate to the directory where eclipse is installed (where the eclipse executable is) you will find a file called eclipse.ini You should put the -XX:MaxPermSize option in here (along with any other vm options that you want to use when for running eclipse).
I don't know exactly what the PermGen space is but it is not the same as the heap size which is governed by the options -Xms -Xmx options. see this page for more information: http://wiki.eclipse.org/FAQ_How_do_I..._to_Eclipse%3F

I have also read that sometimes on linux the eclipse.ini file is not read correctly, with someone else suggesting that each option in the file needs to be on a new line. I'm not sure how you could test to make sure the eclipse.ini is read, but it should be.

It is also be possible to pass these options in manually by launching eclipse from the command line and adding the -vmargs stuff on the command line too: eg

eclipse -vmargs -Xms256m -Xmx512m -XX:MaxPermSize=128m

The PermGen problem tends to occur (afaik) when you have lots of plugins installed, this is why many eclipse users have multiple versions of eclipse with the minimum number of plugins that they need for the particular project.

Hope this helps
