Memory leak

Hello.
I installed last 64x version of RapidMiner and I have some problem with memory leak.
For example I use 8.5 MB data set and I try to build Decision Tree model(default) and at result RapidMiner consume 4Gb+ memory....
When I used ID3 model I got error "out of memory"....
Please help
PS Started RapidMiner consume 400-500Mb without any projects

Hi,

have you read the RapidMiner installation guide?
http://rapid-i.com/content/view/17/211/lang,en/#starting:windows
RapidMiner will try to allocate 80% of the free memory right at the startup with the default settings.

Apart from that, depending on the type of the data set as well as the operation you're trying to do, the needed memory may indeed be quite high.
Out of curiosity: How did you determine the memory usage? Did you use the build-in system monitor?

Regards,
Marco
