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. -- This message was sent by Atlassian JIRA (v6.2#6252)
