What's the limit of the amount of data in RapidMiner?

Hi,

The number of my examples is 10530 and the number of the attributes is about 334. I am running RapidMiner on my desktop. However, it kept freezing. So,  I would like to know whether this is due to the limit of my desktop's memory or it is beyond RapidMiner's ability to handle this amount of data.

Also,  if RapidMiner crashes, is there any way I could retrieve the part of results that RapidMiner has processed?

Thanks a lot!
