PermGem-Ganymede Drivine me crazy! [message #226837]

Hi,

I normally use Eclipse Europa but upgraded to Ganymede because I wanted to
develop web services. I downloaded WebTools plugin etc. Everything is fine
on that front however I keep getting out of memory errors.

I have a dual core laptop with 2Gs of Ram. I cant
develop anything because eclipse keeps crashing due to out of memory error
(PermGen)...pasted below.

I have edited my eclipse.ini file in attempt to overcome this but to no
avail... but I am no expert on this.. any help/ideas appreciated..my .ini
file is
pasted below the error...

Thanks
T

Here is my eclipse.ini

-startup
plugins\org.eclipse.equinox.launcher_1.0.101.R34x_v20080819. jar
--launcher.library
plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.0. 101.R34x_v20080731
-showsplash
org.eclipse.platform
-vmargs
-XX:MaxPermSize=256m
-Xms128m
-Xmx712m

You should increase your PermGenSpace available by modifying this line
"-XX:MaxPermSize=256m"

Your ini is not specifying the JVM, so the --launcher arg may not be
applying. Without telling it, Eclipse will try to find a JVM on your
system; that means you don't really know which one it will get.
Use the -vm parameter to tell it the exact location of your JVM
executable, as described in http://wiki.eclipse.org/Eclipse.ini (pay
careful attention to the format decribed there).

Also, there should be no need to specify permgen space of 512MB; 256MB
is plenty to run Eclipse with Web Tools (and a lot more).

Hope this helps,
Eric
