Re: Region servers goes down all the time...

Is the HBase Web UI up when you get these alerts? Is HBase shell still functional during this?

Have you inspected the RegionServer logs to see what the FATAL message is when it goes down? Its stdout will also carry some messages, if its an OOME situation.
