stack resolved HBASE-508.
-------------------------
Resolution: Invalid
Server does not go on to OOME as we've seen in the past. Later in the log, the
master deployed a new region to this server. This seemed to shake things up.
After all of the opening hysteria around deploy of new region, we did a couple
of flushes on an old region -- were 'normal' 64M in size -- then we went on to
do a compaction and a cleanup of most of the logs we'd just written. It looks
like nothing actually wrong here.
Closing as invalid. Will improve quality of logging as part of another issue.
