I have Server 2008 and Rapidminer 64bit and Im getting outofmemory error.
I have 4gb of ram and rapidminer is using only about 150mb when error happens. (It is showing 63 MB in the right-down box)
I set MAX_JAVA_MEMORY to 3000...
Also rapidminer wont start from the exe and I start lib/rapidminer.jar
You may have to use the script rapidminerGUI.bat to start rapidminer, where you can set the %MAX_JAVA_MEMORY% to a value you like. By default (when you start rapidminer.jar via explorer) javaVM uses only 64mb.
