Hi there- If you're absolutely new to Hbase, you might want to check out the Hbase refGuide in the architecture, performance, and troubleshooting chapters first.
http://hbase.apache.org/book.html In terms of determining why your region servers "just die", I think you need to read the background information then provide more information on your cluster and what you're trying to do because although there are a lot of people on this dist-list that want to help, you're not giving folks a whole lot to go on.
