Description

This has been seen a few times. Master with Xms1g and Xmx4g, which should be more than enough. Most recent case, with 44 nodes, 1.74k tablets, and 22 tables including !METADATA. There are NO conspicuous messages in the master (just DefaultLoadBalancer messages for each table). Possible exception for an error of "received invalid frame size of -..., are you using TTframeProtocol (can't remember exact message). But then the master out file has a message about OoM received, kill -9.

I don't really know how to get more information out of it for when this does occur again.
