> After HBASE-13819 the system some times run out of direct memory whenever there is some network congestion or some client side issues.
> This was because of pending RPCs in the RPCServer$Connection.responseQueue and since all the responses in this queue hold a buffer for cellblock from BoundedByteBufferPool this could takeup a lot of memory if the BoundedByteBufferPool's moving average settles down towards a higher value
