I am using Eclipse 3.1 to code some very large projects (about 3.000
files, most of them .java, but some .xml, .xlst etc., too). To compile,
I am running a very complex ANT script.

Unfortunatley, every one or two hours, the IDE runs out of memory (even
I am running a 1 GB machine, having set "-Xmx 512M" when starting
eclipse.exe). It seems like the IDE is not taking respect of the "-Xmx
512M" because if I remove the switch, its not better and not worse!

When I'm taking a look at Windows' task manager it tells me, eclipse is
not nearly using the 512 megs!

So how can I convince eclipse IDE to really take that 512M I am willing
to reserve for it?

Make sure you use -vmargs -Xmx512M

Actually I am doing this already:

C:\eclipse\eclipse.exe -vmargs -Xmx512M

So what to do now?

BTW, OS is Windows XP Pro SP 2, Java is Sun JDK 1.5.0_06.

You may run out of PermGen space.
You can increase the PermGen space limit with -vmargs
-XX:MaxPermSize=<megabytes>m (default = 64m)

Indeed sometimes it posted the word "PermGen".
Why isn't the VM adopting more "PermGen" when I add -Xmx512M...?
Okay, I'll give it a try!

Thanks
