Hi Andrea, Simone,
I ended up having to install 64bit java (but now don't have native JAI)
as none of the suggestions were working. It wasn't letting me put the xmx
above 1G before, but now I've set it to 3G and its working.
We may end up going with a linux deployment, but for now it'll have to be
Windows.
Thanks both,
Jonathan
