Raghu Angadi commented on HADOOP-2907:
--------------------------------------

DataNode is allowed 1000MB (-Xmx). Top shows virtual memory of around 1.2-1.3 
GB resident is around 50-150MB. I am thinking of running a temporary patch that 
prints some stats when any thread catches OutOfMemoryException, and probably 
block so that we can inspect the process further.
