stack commented on HBASE-9868:
------------------------------
I'm looking at this stuff too. I wonder if some of Elliott's issue in client
was just GCing. I have a 4G heap and running through 1M row cycles, I OOME at
the 4th or 5th run w/ faked 1k servers and 100k regions. Looking for the
root... If I were to guess it'd be the soft reference cache. Will report back.
> Remove some array copy, especially around protobuf
