      Description

      Ivan commented this issue in BOOKKEEPER-461, but seems that the last patch I attached doesn't address this comment.

      https://issues.apache.org/jira/browse/BOOKKEEPER-461?focusedCommentId=13503945&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13503945

      so when publish speed is larger than deliver/consume speed, it might overwhelm readAhead cache and putting lots of collectOldEntries operations in request queue, finally it OOM.
