Nick Dimiduk commented on HBASE-10792:
--------------------------------------
[~enis], [~devaraj]: any objection to including this on hbase-10070 branch?
Local mode testing is basically broken without it.
> RingBufferTruck does not release its payload

> Run a write-heavy workload (PerfEval sequentialWrite) out of a trunk sandbox
> and watch as HBase eventually dies with an OOM: heap space. Examining the
> heap dump shows an extremely large retained size of KeyValue and
> RingBufferTrunk instances. By my eye, the default value of
> {{hbase.regionserver.wal.disruptor.event.count}} is too large for such a
> small default heap size, or the RBT instances need to release their payloads
> after consumers retrieve them.
