Cannot allocate memory MacOS 3.3.2 and 3.4.1 [message #334365]

Getting "Could not reserve enough space for object heap" when running
eclipse at command line. Is this due to Eclipse on Mac not being 64 bit?

eclipse.ini:

-showsplash
org.eclipse.platform
-vmargs
-server
-d64
-Xdock:icon=../Resources/Eclipse.icns
-XstartOnFirstThread
-Xms1g
-Xmx3g
-XX:MaxPermSize=256m
-Dorg.eclipse.swt.internal.carbon.smallFonts

Eclipse 3.5M5, just released, has a 64-bit Cocoa port. Of course, this is
an in-development milestone release, so you can decide for yourself whether
that is stable enough (and supported by enough third-party plugins) for your
needs.

As far as I know there is no 64-bit version of Eclipse 3.4 for Mac.
Information about supported platforms for Eclipse 3.4 is at
http://www.eclipse.org/eclipse/development/eclipse_project_p lan_3_4.html#TargetOperatingEnvironments .

You should be able to run a 32-bit eclipse release on 64-bit OS X iff your
VM is 32-bit. If your VM is jre 1.6 then this is not the case since it's
only available in a 64-bit flavour, but if it's pre-1.6 then it could be.
I've never heard of the error you're seeing before, so I'm just guessing
that you have a bit mismatch between your VM and eclipse.

You are trying to allocate 1G of memory at the start. This is quite large.
Try reducing the value to something smaller and see if it helps.
