Fixing Out of Memory Errors with Eclipse 3.2, Mac OS X

I've recently been getting out of memory errors with Eclipse 3.2 on Mac OS X. Initially, I bumped the maximum heap size to 512MB, but that wasn't sufficient. I then saw that the problem was actually with the PermGen size. So I bumped that up from the default 64MB to 128MB. So far so good.

On OS X, you change these settings by editing Eclipse.app/Contents/MacOS/eclipse.ini. There I set -Xmx to 512m and I added a parameter, -XX:MaxPermSize, and set it to 128m. My complete eclipse.ini file is here:

-vmargs
-Xdock:icon=../Resources/Eclipse.icns
-XstartOnFirstThread
-Xbootclasspath/p:../../../plugins/org.eclipse.jdt.debug_3.2.0.v20060605/jdi.jar-Xms40m
-Xmx512m
-XX:MaxPermSize=128m
