Re: [Dltk-dev] Performance issue

["didier barzin" <didier@xxxxxxxxx>]

Hi,

I have a memory overflow in ScriptReconciler :

Exception in thread
"org.eclipse.dltk.internal.ui.text.ScriptReconciler"
java.lang.OutOfMemoryError: Java heap space

I am using the last DLTK Integration build with Eclipse 3.4.0

I have tried to stat the plugin with these arguments, without sucess :

-vmargs -Xmn100M -Xms500M -Xmx500M
