Robert Stupp resolved CASSANDRA-13754.
--------------------------------------
Resolution: Fixed
[~urandom], it's not about the {{BTree.Builder}} instances, it's about what's
kept referenced by those - and that is the bunch of {{HeapByteBuffer}}
instances, as reported by [~markusdlugi] and fixed by the patch for this
ticket. The screenshot you attached, matches the fixed issue. Therefore, I
recommend to try the patch or a build from the recent 3.11/trunk branches and
test again. Going go resolve this issue. If it's really something else that's
causing the issue, I'd prefer to open another ticket, because there is already
something committed for this ticket that addresses a very particular issue.
