Massive Ram Consumption

Guilty: apache, mysql and java.

As far as i can see, even with a little bit tuning, these three candidates consume every free bit of my RAM

Everythings runnig fine, except the fact, that i can´t add users:

$ /opt/open-xchange/sbin/createcontext -A oxadminmaster -P admin_master_password -c 1 \
-u oxadmin -d "Context Admin" -g Admin -s User -p admin_password -L defaultcontext \
-e oxadmin@example.com -q 1024 --access-combination-name=all

...gives me an java error, not enough memory heap

Hey there, i really need a helping hand

Currently i have not a single KB of RAM left on my VS (after succesfull installation of OX).
