Hi Fabio,

finally managed to do a 554MB heapdump and uploaded it to
http://rekveld.home.xs4all.nl/stuff
(i have to run now and it still has 30mins of uploading to go)

I modified the settings a bit in order to avoid having to upload a 1.2GB dump,
but I don't think that makes a difference for tracking down the problem.

And for those who ever need to do this, what I figured out is to add these two
lines to your eclipse.ini file. The last one specifies the directory and it
is wise to make a directory especially for it, since the analysis produces lots
of little files you don't want to pollute your working directory or home folder.
It took me a while to find this out, since all the documentation is mostly explaining
you how to find memoryleaks in your own code, not in the IDE you're using.

I had a look and it seems to have to do with code analysis. A couple of times
Eclipse froze on completing an Open_GL attribute, and in the system monitor
I could see it filling up 1.2G of memory in 2 or 3 minutes.
