My FlashBuilder instance continues to crash when performing large profiling. I must say that I also generate a trace of the selection of objects (everything, not the default 10) and a lot of moving GC paths.
However, I have a hunch that I can solve this problem by providing Flash Builder with more memory.
This is my FlashBuilder.ini:
-startup eclipse/plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar --launcher.library eclipse/plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.100.v20110502 --launcher.defaultAction openFile -nl en_US -vmargs -Xms256m -Xmx1024m -XX:MaxPermSize=256m -XX:PermSize=64m -Dorg.eclipse.equinox.p2.reconciler.dropins.directory=eclipse/dropins -Declipse.application=com.adobe.flexbuilder.standalone.FlashBuilderApplication
In my eclipse error log I can clearly see:
java.lang.OutOfMemoryError: requested 1024000 bytes for GrET in C:\BUILD_AREA\jdk6_16\hotspot\src\share\vm\utilities\growableArray.cpp. Out of swap space?
Here is the complete error log:

All this leads me to the conclusion that there should be something wrong with my Xms / Xmx / MaxPermsize / PermSize settings .
I know that increasing Xmx to more than 1024 m will lead to additional crashes / unwanted behavior.
Does anyone have any ideas what ideal values should be?
Any pointers to this question would be greatly appreciated.
