stack updated HBASE-11678:
--------------------------
Attachment: gc_over_12_hours_unevenblocks_with_lots_of_evictions.png
Ran for 12 hours. GC plot looks clean. It may be tending up slightly... will
run for longer next time but looking at heap dump, this ramCache issue is no
longer the culprit.
Looking to make a unit test. Its a bit awkward given how deep down doDrain is
inside BucketCache but worth doing I'd say.

> Testing BucketCache, my heap filled after running for hours. Dumping heap,
> culprit is the ramCache Map in BucketCache. Tried running with more writer
> threads but made no difference. Trying to figure now how our accounting is
> going wonky.
